    Objective The clinical presentation of anorexia nervosa (AN) is characterized by preoccupation with body experience, intrusive concerns regarding shape, and pathological fears of weight gain. These symptoms are suggestive of unrelenting self-focused attention. No research to date has characterized self-focused attention (SFA) in AN nor examined neurocognitive features that may facilitate an excessive, rigid, or sustained focus on one’s appearance. Method This study examined SFA, body image disturbance, and executive functioning in women with current anorexia nervosa (AN-C; n = 24), a history of AN who were weight-restored at the time of the study weight-restored (WR; n = 19), and healthy controls (n = 24). Results Private and public SFA were highest among WR and lowest among AN-C. Shape concerns were negatively correlated with SFA, especially among AN-C, after controlling for depression and social anxiety symptoms. Discussion Lower levels of SFA among AN-C were unexpected and suggest the acute state of AN may lessen pathological self-focus, negatively reinforcing symptoms. In addition, body image concerns may distract from general SFA. Deficits in executive attention may explain these findings, as each one unit increase in perseverative errors among AN-C participants was associated with an almost one-half unit decrease in public SFA.

    2011-01-01

    Full Text Available Research progress assessing the role of attentional focusing instructions on skill acquisition and performance has lead researchers to apply this approach to force production tasks. Initial converging evidence indicates that force production tasks are sensitive to verbal instruction; externally focused instructions (onto movement outcomes, or onto the object force is being exerted against are shown to be more beneficial than internally focused instructions (focusing attention onto the movements being executed. These benefits are observed for maximal and accurate force production, as well as the maintenance of force production in prolonged tasks. A range of mechanisms are identified supporting the proposal that an external focus promotes movement efficiency in line with energy and effort conservation. Future research is required to assess how this developing body of work interacts with the broader understanding of psychological and physiological factors implicated in the effective production, maintenance and limitation of maximal or sub-maximal forces.

    Research addressing the influence of happy mood on self-focused attention has yielded inconsistent results. Some studies found that happy mood decreased self-focus relative to sad mood. Other studies did not detect a significant difference between happy and neutral mood, and still other studies found that happy mood, relative to neutral mood, increased self-focus. These investigations have potential shortcomings, such as an insufficiently powerful happy mood induction and a confound between visualization mood inductions and self-focus itself. The present experiment addressed these shortcomings by inducing mood via musical selections, equalizing the approximate potency between happy and sad moods, and using a within-participants design. Relative to neutral mood, happy mood decreased self-focused attention.

    Neuroticism and negative affect have been associated with an increase in attentional investment and the greater processing of irrelevant stimuli. Previous research proposes the overinvestment of attention and a focused mental state as the mechanism of this effect. We investigated the neural correlates of this idea using a dual-stream rapid serial visual presentation paradigm with centrally presented, overlapping streams of letters that changed at different frequencies. Participants attended one stream at a time. We predicted that the more focused cognitive style associated with higher neuroticism would be reflected in the overinvestment of attention in the irrelevant stream of to-be-ignored letters, in particular, when the ignored stream was the more salient one. This was expected to lead to a smaller difference in power between the attended and unattended frequencies. Results showed that power differences between attended and unattended streams were negatively correlated with neuroticism scores in direct support of our hypothesis. Exploratory correlations also showed that extraversion was positively related to the attention difference. As extraversion has been contrasted to neuroticism and linked to increased cognitive flexibility and control in previous studies, it is possible that this trait may help in disengagement from salient stimuli. Together, these results provide the first neural correlates of the focused cognitive style idea. That the effect of extraversion is seen in the centro-parietal region and the effect of neuroticism is seen in the occipital region, indicate that these personality traits may affect the hierarchy of visual information processing. These findings provide new insight into the influence of personality traits on attention mechanisms and open up questions regarding the relationship between neuroticism, extraversion and information processing.

  7. [Strategic focusing of attention during narrative reading].

    In 2 experiments based on the constructionist view of text comprehension, we investigated whether readers are able to strategically use, in a problem solving matter, spatial and temporal information that varies in its relevance to the goals of the protagonists. In order to accomplish this, we varied the specificity of the protagonists' goal descriptions. Both experiments consisted of a reading section, a test, and a questionnaire, and differed only in respect to when the questionnaire was administered. The results of both experiments showed that readers were able to use spatial and temporal information of narrative texts in a strategic matter, and they even did so without explicit instruction. This focus of attention, however, was not uniformly reflected in the reading times. Memory data showed a clear disadvantage for temporal information as compared to spatial information. This was the case even though both types of information had been equally well identified in the questionnaire as crucial to the problem solving process of the protagonist.

    Ostracism-being excluded and ignored-thwarts satisfaction of four fundamental needs: belonging, self-esteem, control, and meaningful existence. The current study investigated whether training participants to focus their attention on the here-and-now (i.e., focused attention) reduces distress from an ostracism experience. Participants were first trained in either focused or unfocused attention, and then played Cyberball, an online ball-tossing game for which half the participants were included or ostracized. Participants reported their levels of need satisfaction during the game, and after a short delay. Whereas both training groups experienced the same degree of need-threat in the immediate measure, participants who were trained in focused attention showed more recovery for the delayed measure. We reason that focused attention would not reduce the distress during the ostracism experience, but it aided in recovery by preventing participants from reliving the ostracism experience after it concludes.

    Healthy dextrals underwent fMRI during a task of graphesthesia requiring detection of any number written consecutively from an otherwise random number sequence. Test conditions included (1) focus on unilateral right hand stimuli, (2) focus on unilateral left hand stimuli, (3) focus on right hand only during bilateral hand stimulation, (4) focus on left hand only during bilateral hand stimulation, and (5) rest. Attention to unilateral hand stimulation produced bihemispheric activation with minimal or no activation of ipsilateral primary sensorimotor region. Attention to unilateral left hand stimuli resulted in more activation than attention to unilateral right hand stimuli. Stimulation of the nonattended hand activated the contralateral somatosensory area, but to a lesser spatial extent than attended stimuli. Comparing focused attention to the left versus right side during identical sensory inputs (i.e., bilateral hand stimulation), focused attention to the right hand increased activation in the left somatosensory region, but focused attention to the left hand increased activation in both cerebral hemispheres. Thus, focused attention to unilateral somatosensory stimuli produces bilateral cerebral activation, but the increase in blood flow is greater in the contralateral hemisphere. Unattended stimuli activate the contralateral primary somatosensory area. Left/right asymmetries were demonstrated consistent with cerebral lateralization.

    Considerable evidence supports the motor learning advantage associated with an external focus of attention; however, very few studies have investigated attentional focus effects with children despite individual functional constraints that have the potential to impact use of instructional content. Thus, the purpose of this study was to determine the effect of attentional focus instruction on motor learning in children. Participants (n=42) aged 9-11years were randomly assigned to one of three gender-stratified groups: (1) control, (2) internal focus, or (3) external focus. Following initial instructions and task demonstration, participants performed 100 modified free throws over two days while receiving additional cues respective to their attentional focus condition and returned approximately 48h later to perform 20 additional free throws. Results revealed no significant learning differences between groups. However, responses to retrospective verbal reports suggest that the use of external focus content during practice may have contributed to some participants' superior performance in retention. Future research should continue to examine attentional focus effects across a variety of ages and incorporate retrospective verbal reports in order to examine children's thoughts during attentional focus instruction.

  15. Laterally focused attention modulates asymmetric coupling in rhythmic interlimb coordination.

    Peters (J Motor Behav 21:151-155, 1989; Interlimb coordination: neural, dynamical and cognitive constraints, Academic, Orlando, pp 595-615, 1994) suggested that expressions of handedness in bimanual coordination may be reflections of an inherent attentional bias. Indeed, previous results indicated that focusing attention on one of the limbs affected the relative phasing between the limbs in a manner comparable to the effects of hand dominance. The present study extended the comparison between the effects of attentional focus and handedness by testing their impact on the interactions between the limbs. Both left-handed and right-handed participants performed rhythmic bimanual coordination tasks (in-phase and antiphase coordination), while directing attention to either limb. Using brief mechanical perturbations, the degree to which the limbs were influenced by each other was determined. The results revealed that the non-dominant limb was more strongly affected by the dominant limb than vice versa and that, in line with Peters' proposition, this handedness-related asymmetry in coupling strength was reduced when attention was focused on the non-dominant limb, thereby highlighting the potential relation between inherent (handedness-related) asymmetries and voluntary attentional asymmetries. In contrast to previous findings, the (commonly observed) phase lead of the dominant limb was attenuated (rather than accrued) when attention was focused on this limb. This unexpected result was explained in terms of the observed attention-related difference in amplitude between the limbs.

    A clinical protocol based on contemporary cognitive behavioral treatment for social anxiety was developed and examined. Previously published instructions for conducting a focus-of-attention behavioral experiment targeting self-focused attention and safety behaviors during exposure were used to create a structured protocol. Individuals (n = 45) with high levels of social anxiety and public-speaking anxiety were randomly assigned to either a focus-of-attention behavioral experiment (FABE) or an Exposure-Only Control (EOC) condition. During four exposure trials, those in the FABE condition (n = 24) were alternately instructed to engage in self-focused attention vs. externally focused attention and to eliminate safety behaviors. Those in the EOC condition (n = 21) were not so instructed. At post-intervention, individuals in the FABE condition showed significantly less self-focused attention and anxiety, and better observed performance as rated by audience members. Focus-of-attention statistically mediated the effect of condition on anxiety. For those in the FABE condition, the degree of association between focus-of-attention and anxiety during the intervention predicted less self-focused attention post-intervention. The FABE appears to be a useful procedure for implementing part of the contemporary cognitive behavioral treatment model.

    Schutts, KS, Wu, WFW, Vidal, AD, Hiegel, J, and Becker, J. Does focus of attention improve snatch lift kinematics? J Strength Cond Res 31(10): 2758-2764, 2017-Recent motor control literature has demonstrated that using verbal instructions to direct a performer's attention externally (i.e., toward the movement outcome) enhances motor skill performance. The purpose of this study was to investigate how an athlete's focus of attention impacts kinematic performance of the snatch. Using a counterbalanced within-participant design, 12 competitively trained athletes (8 male and 4 female athletes) performed 2 instructional blocks of 3 snatch repetitions at 80% of their most recent training 1 repetition maximum. Blocks of internal and external instructions were given to the athlete in a random fashion. Results showed that, when focusing internally, athletes significantly (p ≤ 0.05) increased elbow velocity relative to focusing externally, whereas the external instructions significantly increased horizontal barbell velocity, relative to internal instructions. Additionally, an internal focus resulted in significantly larger barbell-cervical-hip angles at maximum height of the barbell compared with an external focus, indicating that the athletes squatted under the barbell too soon. This information adds to the literature suggesting small changes in coaching instructions can impact performance significantly. It is recommended that coaches use instructions that direct an athlete's attention externally, toward the movement outcome, rather than the action itself.

    This manuscript presents two experiments designed to explore the effects of attention on perceived exertion and time to failure in a fatiguing athletic task. There were two major motivating factors for these experiments. First, there are few studies evaluating attentional focus effects in endurance tasks and, second, there is a lack of integration between studies of attentional focus as external/internal (e.g., Wulf, 2007a) compared to associative/dissociative (e.g., Stevinson and Biddle, 1998). In Experiment 1, we used a fatiguing wall-sit posture (essentially a complex, isometric task) to compare two different types of external attention with an internal focus on the position of the legs. An external focus (regardless of type) increased the time taken to failure and reduced perceived exertion. In Experiment 2, we manipulated subjects' expectancy of fatigue to test the interaction of attention and expectancy (both top-down factors) in this highly fatiguing task. Previous theories of attention during endurance tasks have suggested that as fatigue/pain increase, bottom-up factors begin to dominate subjects' attention. While this may be true, Experiment 2 showed that even in a highly fatiguing task, attentional strategies, and expectancies affected the time to failure and perceived exertion.

    2016-03-01

    Focus of attention and its effects on skilled motor performance has become an important line of research in the motor learning domain. Numerous studies have demonstrated that an external focus of attention (i.e., on the movement effect) enhances motor performance and learning relative to an internal focus (i.e., on body movements). Thus, small differences in the wording of instructions or feedback given by teachers can have a significant impact on the effectiveness and efficiency of motor skill performance. In this paper, we review some of the attentional focus studies that are relevant to ballet performance. In addition, we report the findings of a survey among professional ballet dancers (N = 53) that we conducted to determine their typical attentional focus while performing certain movements. The results showed that the majority adopted internal foci, or combinations of internal and external foci, most of the time. This suggests that there is room for improvement for performance and teaching. We provide examples of how external foci can be promoted in ballet practice.

  3. Differences in Attentional Focus Associated With Recovery From Sports Injury: Does Injury Induce an Internal Focus?

    2015-12-01

    Although it is commonly believed that focusing too much attention on the injured body area impairs recovery in sports, this has not been directly assessed. The present study investigated attentional focus following sports injury. Experienced baseball position players recovering from knee surgery (Expt 1) and baseball pitchers recovering from elbow surgery (Expt 2) performed simulated batting and pitching respectively. They also performed three different secondary tasks: leg angle judgments, arm angle judgments, and judgments about the ball leaving their bat/hand. Injured athletes were compared with expert and novice control groups. Performance on the secondary tasks indicated that the injured batters had an internal focus of attention localized on the area of the injury resulting in significantly poorer batting performance as compared with the expert controls. Injured pitchers had a diffuse, internal attentional focus similar to that of novices resulting in poorer pitching performance as compared with the expert controls.

    Mindfulness meditation techniques are increasingly popular both as a life-style choice and therapeutic adjunct for a range of mental and physical health conditions. However, little is known about the mechanisms through which mindfulness meditation and its constituent practices might produce positive change in cognition and emotion. Our study directly compared the effects of Focused Attention (FA) and Open-Monitoring (OM) meditation on alerting, orienting and executive attention network function in healthy individuals. Participants were randomized to three intervention groups: open-focused meditation, focused attention, and relaxation control. Participants completed an emotional variant of the Attention Network Test (ANT) at baseline and post-intervention. OM and FA practice improved executive attention, with no change observed in the relaxation control group. Improvements in executive attention occurred in the absence of change in subjective/self-report mood and cognitive function. Baseline levels of dispositional/trait mindfulness were positively correlated with executive control in the ANT at baseline. Our results suggest that mindfulness meditation might usefully target deficits in executive attention that characterise mood and anxiety disorders.

    The two preeminent cognitive behavioral models of social anxiety [Clark, D.M., & Wells, A., (1995). A cognitive model of social phobia. In Heimberg, R.G., Liebowitz, M., Hope, D.A., and Schneier, F.R. (Eds.), Social phobia: Diagnosis, assessment and treatment (pp. 69-93). New York: Guilford Press.; Rapee, R.M., & Heimberg, R.G., (1997). A cognitive behavioral model of anxiety in social phobia. Behaviour Research and Therapy, 35, 741-756.] suggest that attention to threat stimuli is critical in the maintenance of social fear. However, Clark and Wells assert that socially anxious persons attend almost exclusively to negative thoughts and self-imagery during social situations, whereas Rapee and Heimberg contend that socially anxious persons simultaneously attend to these internal cues and external stimuli potentially indicative of negative evaluation, such as an audience member's facial expressions. Rapee and Heimberg further suggest that attention to external and internal cues during social situations should be interdependent, such that focus on one has causal implications for the experience of the other. The current review examines the nature of the literature as it supports the assertions of each of these models of social anxiety, with particular attention to differing predictions regarding attentional focus. We conclude that socially anxious persons engage in both internal and external focus throughout the course of a social situation; however, there are a number of significant limitations to the literature. Accordingly, directions for future research are considered.

  6. The Focus of Attention in Visual Working Memory: Protection of Focused Representations and Its Individual Variation

    Visual working memory can be modulated according to changes in the cued task relevance of maintained items. Here, we investigated the mechanisms underlying this modulation. In particular, we studied the consequences of attentional selection for selected and unselected items, and the role of individual differences in the efficiency with which attention is deployed. To this end, performance in a visual working memory task as well as the CDA/SPCN and the N2pc, ERP components associated with visual working memory and attentional processes, were analysed. Selection during the maintenance stage was manipulated by means of two successively presented retrocues providing spatial information as to which items were most likely to be tested. Results show that attentional selection serves to robustly protect relevant representations in the focus of attention while unselected representations which may become relevant again still remain available. Individuals with larger retrocueing benefits showed higher efficiency of attentional selection, as indicated by the N2pc, and showed stronger maintenance-associated activity (CDA/SPCN). The findings add to converging evidence that focused representations are protected, and highlight the flexibility of visual working memory, in which information can be weighted according its relevance.

    We investigated whether the emotional content of visual scenes depicting people is processed in peripheral vision. Emotional or neutral scene photographs were paired with a matched scrambled image for 150ms in peripheral vision (≥5°). The pictures were immediately followed by a digit or letter in a discrimination task. Interference (i.e., slowed reaction times) with performance in this task indexed the processing resources drawn by the pictures. Twelve types of specific emotional scene contents (e.g., erotica or mutilation) were compared. Results showed, first, that emotional scenes caused greater interference than neutral scenes, in the absence of fixations. This suggests that emotional scenes are processed and draw covert attention outside the focus of overt attention. Second, interference was similar for female and male participants with pleasant scenes (except for erotica), but females were more affected by all types of unpleasant scenes than males. This reveals that sensitivity to peripheral vision is modulated by sex and affective valence. Third, low-level image properties, visual saliency, and size of bodies and faces, were generally equivalent for emotional and neutral scenes. This rules out the alternative hypothesis of a contribution of non-emotional, purely perceptual factors. Copyright © 2015 Elsevier B.V. All rights reserved.

  9. Attentional Focus Effects in Standing Long Jump Performance: Influence of a Broad and Narrow Internal Focus.

    2015-07-01

    The content of instructions that strength coaches give can have a significant impact on how an athlete or client performs. Research on motor learning has shown an advantage of instructions focusing on the effects of movements (external focus) over those focusing on the movements themselves (internal focus) in the performance of motor skills. Internally focused cues are abundant in coaching, therefore the purpose of this study was to test whether some internally focused cues might be more helpful than others. Participants (68) were randomly assigned to either an external focus (EX), broad internal focus (B-IN), narrow internal focus (N-IN), or a control group (CON), and performed 5 standing long jumps. All groups were instructed that the goal was to jump as far as possible. In addition, the EX group was told to "jump as far past the start line as possible." The B-IN group was told to "use your legs." The N-IN group was told to "extend your knees as rapidly as possible," and the CON group received no additional instruction. An analysis of covariance showed that the EX group (198.09 ± 31.89 cm) jumped significantly farther than both the B-IN group (173.74 ± 35.36 cm), p = 0.010 and the N-IN group (178.53 ± 31.17 cm), p = 0.049, with no group different from the CON group. The results suggest that a broad internal focus is no more effective than a narrow internal focus, and that an external focus leads to the greatest jump distance. Strength and conditioning professionals should carefully word their instructions to induce an external focus of attention whenever possible.

    Full Text Available Meditation is becoming increasingly popular as a topic for scientific research and theories on meditation are becoming ever more specific. We distinguish between what is called Focused Attention meditation, Open Monitoring meditation, and Loving kindness (or compassion meditation. Research suggests that these meditations have differential, dissociable effects on a wide range of cognitive (control processes, such as attentional selection, conflict monitoring, divergent and convergent thinking. Although research on exactly how the various meditations operate on these processes is still missing, different kinds of meditations are associated with different neural structures and different patterns of electroencephalographic activity. In this review we discuss recent findings on meditation and suggest how the different meditations may affect cognitive processes and we give suggestions for directions of future research.

    Full Text Available EEG biofeedback (so called neurofeedback is considered as an efficacious treatment for ADHD. We propose that operant conditioning of EEG in neurofeedback training mode, aimed to mitigate inattention and low arousal in ADHD, will be accompanied by changes in EEG bands' relative power. Patients were 18 children diagnosed with ADHD. The neurofeedback protocol (“Focus/Alertness” by Peak Achievement Trainer, Neurotek, KY used to train patients has focused attention training procedure, which according to specifications, represents wide band EEG amplitude suppression training. Quantitative EEG analysis was completed on each of 25 min long twelve sessions to determine the relative power of each of the EEG bands of interest throughout each session, and from the first session to the last session. Additional statistical analysis was performed to determine significant changes in relative power within sessions (from minute 1 to minute 25, and between sessions (from session 1 to session 12 for an individual patient. We performed analysis of relative power of Theta, Alpha, Low and High Beta, Theta/Alpha, Theta/Beta, and Theta/Low Beta and Theta/High Beta ratios. We performed also analysis between the “Focus”measure and changes in relative power of above EEG rhythms and their ratios. Additional secondary measures of patients’ post-neurofeedback outcomes were assessed using an audio-visual selective attention test (IVA + Plus and behavioral evaluation scores from Aberrant Behavior Checklist. We found that, as expected, Theta/Low Beta and Theta/Alpha ratios decreased significantly from Session 1 to Session 12 and from minute 1 to minute 25 within sessions. The ‘Focus” measure of protocol showed high negative correlation with both Theta/Alpha and Theta/Beta ratios. The findings regarding EEG changes resulting from self-regulation training along with behavioral evaluations will help in elucidation of neural mechanisms of neurofeedback aimed to improve

    Indeed, the more one reflects on this question, the clearer it becomes that one will never be able to bring the public around to a full support of things nuclear until they truly understand the incredible benefits inherent in this marvelous technology. Arguments centered on low risk will continually fall on either deaf or skeptical ears until the public is awakened to the enormous benefits they already derive from nuclear technology. Tempting though it may be to spent time and energy formulating and defending issue statements, the reality is that the public and most policy makers will simply not pay attention until they become aware of how ubiquitous radiation has become in enriching their daily lives. But, how does one get their attention? How can nuclear technologists penetrate the apathy that is exemplified by the glazed eyes normally encountered whenever one attempts to reach meaningful numbers of the public? How does one get the attention of the American people in a positive sense? Whereas one dare not make premature claims, the authors two activities that hold instant appeal to most Americans: (a) publicizing a real hero and (b) holding a celebration. It was on this premise that a decision was made in May 1998 to launch the concept of celebrating the centennial discovery of radium by Marie Curie. The initial response has been no less than staggering. Why? How could an event associated with things nuclear garner such positive attraction? Since the main events are not scheduled to take place until the year 2000, it is too early to claim success. But, by featuring the most famous female scientist of modern times, combined with a natural time of celebration, they believe they have successfully created a combination that has almost a magical attraction. People hearing of the project for the first time naturally begin to ask questions and explore possibilities, and the enthusiasm becomes contagious. They all known they have a powerful story to tell, if only they

    2017-01-01

    This study aims to elucidate the intricate interplay between public attention and public emotion toward multiple social issues. A theoretical framework is developed based on three perspectives including endogenous affect hypothesis, affect transfer hypothesis, and affective intelligence theory. Large-scale longitudinal data with 265 million tweets on five social issues are analyzed using a time series analytical approach. Public attention on social issues can influence public emotion on the issue per se. Social issues interact with one another to attract public attention in both cooperative and competitive ways. Instead of a direct transfer from public emotion to public attention, the public emotion toward a social issue moderates the interaction between the issue and other issue(s). PMID:28081117

    Full Text Available In the times of the Polish People’s Republic, national security issues and, at the same time, surveillance of the society and suppression of many institutions – the Catholic Church included - were in the hands of appropriate services, modelled on the Soviet NKVD. At first this was the Ministry of Public Security and since 1956 the Security Police. The first part of the article presents the organization of security units in the voivodship of Cracow and the distribution of monastic communities, while the second throws light on the activities of these units uh the basis of preserved reports sent from Cracow to the Ministry of Public Security and the Ministry of Internal Affairs. Officials of the Security Police who worked in the voivodship and district departments took a close interest in the Discalced Carmelite monks, taking account of their wartime past, pastoral activity and connections with the Church hierarchy. To ensure influence upon the life of the Discalced Carmelite Province as well as access to information on monastic internal issues they gained several secret collaborators within the congregation itself and its lay associates. The article is the first attempt at showing the methods of the Security Police (SB and the Security Office (UB activities directed at monastic orders; methods aiming at subjugating to the authorities not only the orders themselves, but the whole Catholic Church in Poland.

  19. Pupil size reflects the focus of feature-based attention.

    Binda, Paola; Pereverzeva, Maria; Murray, Scott O

    2014-12-15

    We measured pupil size in adult human subjects while they selectively attended to one of two surfaces, bright and dark, defined by coherently moving dots. The two surfaces were presented at the same location; therefore, subjects could select the cued surface only on the basis of its features. With no luminance change in the stimulus, we find that pupil size was smaller when the bright surface was attended and larger when the dark surface was attended: an effect of feature-based (or surface-based) attention. With the same surfaces at nonoverlapping locations, we find a similar effect of spatial attention. The pupil size modulation cannot be accounted for by differences in eye position and by other variables known to affect pupil size such as task difficulty, accommodation, or the mere anticipation (imagery) of bright/dark stimuli. We conclude that pupil size reflects not just luminance or cognitive state, but the interaction between the two: it reflects which luminance level in the visual scene is relevant for the task at hand.

    In spoken language, pitch accent can mark certain information as focus, whereby more attentional resources are allocated to the focused information. Using functional magnetic resonance imaging, this study examined whether pitch accent, used for marking focus, recruited general attention networks during sentence comprehension. In a language task, we independently manipulated the prosody and semantic/pragmatic congruence of sentences. We found that semantic/pragmatic processing affected bilateral inferior and middle frontal gyrus. The prosody manipulation showed bilateral involvement of the superior/inferior parietal cortex, superior and middle temporal cortex, as well as inferior, middle, and posterior parts of the frontal cortex. We compared these regions with attention networks localized in an auditory spatial attention task. Both tasks activated bilateral superior/inferior parietal cortex, superior temporal cortex, and left precentral cortex. Furthermore, an interaction between prosody and congruence was observed in bilateral inferior parietal regions: for incongruent sentences, but not for congruent ones, there was a larger activation if the incongruent word carried a pitch accent, than if it did not. The common activations between the language task and the spatial attention task demonstrate that pitch accent activates a domain general attention network, which is sensitive to semantic/pragmatic aspects of language. Therefore, attention and language comprehension are highly interactive.

  4. External attentional focus enhances movement automatization: a comprehensive test of the constrained action hypothesis.

    Kal, E C; van der Kamp, J; Houdijk, H

    2013-08-01

    An external focus of attention has been shown to result in superior motor performance compared to an internal focus of attention. This study investigated whether this is due to enhanced levels of movement automatization, as predicted by the constrained action hypothesis (McNevin, Shea, & Wulf, 2003). Thirty healthy participants performed a cyclic one-leg extension-flexion task with both the dominant and non-dominant leg. Focus of attention was manipulated via instructions. The degree of automatization of movement was assessed by measuring dual task costs as well as movement execution parameters (i.e., EMG activity, movement fluency, and movement regularity). Results revealed that an external focus of attention led to significantly better motor performance (i.e., shorter movement duration) than an internal focus. Although dual task costs of the motor task did not differ as a function of attentional focus, cognitive dual task costs were significantly higher when attention was directed internally. An external focus of attention resulted in more fluent and more regular movement execution than an internal focus, whereas no differences were found concerning muscular activity. These results indicate that an external focus of attention results in more automatized movements than an internal focus and, therefore, provide support for the constrained action hypothesis.

  7. Safe practice of population-focused nursing care: Development of a public health nursing concept.

    Science.gov (United States)

    Issel, L Michele; Bekemeier, Betty

    2010-01-01

    Patient safety, a cornerstone of quality nursing care in most healthcare organizations, has not received attention in the specialty of public health nursing, owing to the conceptual challenges of applying this individual level concept to populations. Public health nurses (PHNs), by definition, provide population-focused care. Safe practice of population-focused nursing care involves preventing errors that would affect the health of entire populations and communities. The purpose of this article is to conceptually develop the public health nursing concept of safe practice of population-focused care and calls for related research. Key literature on patient safety is reviewed. Concepts applying to population-focused care are organized based on Donabedian's Framework. Structural, operational and system failures and process errors of omission and commission can occur at the population level of practice and potentially influence outcomes for population-patients. Practice, research and policy implications are discussed. Safe PHN population-focused practice deserves attention.

  8. Stay Focused! The Effects of Internal and External Focus of Attention on Movement Automaticity in Patients with Stroke.

    Dual-task performance is often impaired after stroke. This may be resolved by enhancing patients' automaticity of movement. This study sets out to test the constrained action hypothesis, which holds that automaticity of movement is enhanced by triggering an external focus (on movement effects), rather than an internal focus (on movement execution). Thirty-nine individuals with chronic, unilateral stroke performed a one-leg-stepping task with both legs in single- and dual-task conditions. Attentional focus was manipulated with instructions. Motor performance (movement speed), movement automaticity (fluency of movement), and dual-task performance (dual-task costs) were assessed. The effects of focus on movement speed, single- and dual-task movement fluency, and dual-task costs were analysed with generalized estimating equations. Results showed that, overall, single-task performance was unaffected by focus (p = .341). Regarding movement fluency, no main effects of focus were found in single- or dual-task conditions (p's ≥ .13). However, focus by leg interactions suggested that an external focus reduced movement fluency of the paretic leg compared to an internal focus (single-task conditions: p = .068; dual-task conditions: p = .084). An external focus also tended to result in inferior dual-task performance (β = -2.38, p = .065). Finally, a near-significant interaction (β = 2.36, p = .055) suggested that dual-task performance was more constrained by patients' attentional capacity in external focus conditions. We conclude that, compared to an internal focus, an external focus did not result in more automated movements in chronic stroke patients. Contrary to expectations, trends were found for enhanced automaticity with an internal focus. These findings might be due to patients' strong preference to use an internal focus in daily life. Future work needs to establish the more permanent effects of learning with different attentional foci on re-automating motor control

  9. Thoughts and attention of athletes under pressure: skill-focus or performance worries?

    2011-01-01

    Choking under pressure in sport has been explained by either explicit attention to skill execution (self-focus theories), or attention to performance worries (distraction theories). The aim of the present study was to find out which focus of attention occurs most often when expert athletes perform under pressure. Two retrospective methods were employed, namely, verbal reports and concept mapping. In the verbal reports, 70 expert athletes indicated their main focus of attention when performing under high pressure in competition. For concept mapping seven expert athletes generated statements about their focus of attention in such high-pressure situations. These statements were clustered and rated on how often they occurred and how important they were for choking. Both methods revealed that under pressure attention of expert athletes was often focused on worries and hardly ever on movement execution. Furthermore, the athletes reported that they focused attention on external factors and that they reverted to positive monitoring in an attempt to maintain performance. These results are more in line with distraction theories than self-focus theories, suggesting that attention to performance worries rather than to skill execution generally explains choking.

    2013-01-01

    Several researchers have demonstrated that an external focus of attention (about movement's effects) during movement execution allowed better performances and learning of various motor tasks than an internal focus of attention (about movement itself). However, attentional focus effects have not been studied in tasks requiring explosive actions preceded by fast reaction time to a signal, such as a sprint start. We hypothesised that the beneficial effect of external focus of attention would be observed in the different stages of the sprint start (i.e., reaction time, block clearance and running) for both expert and novice sprinters. Novice and expert sprinters performed sprint starts followed by a 10 m sprint under three conditions: external focus instructions; internal focus instructions; and neutral instructions. The reaction time and the running time were significantly shorter in the external focus condition than in the internal focus condition, for both expert and novice participants. These results confirm the beneficial effect of an external focus of attention on the speed of movement execution. Moreover, they revealed that attentional focus influences movement preparation. Several hypotheses are proposed to account for these results, with reference to the processes that could be responsible for the observed effects.

  11. Age, task complexity, and sex as potential moderators of attentional focus effects.

    Becker, Kevin; Smith, Peter J K

    2013-08-01

    The study tested whether age, sex, or task complexity moderate the effect of attentional focus on motor learning. Children (24 boys, 24 girls) and adults (24 men, 24 women) were assigned to an internal or external attentional focus, and were timed while riding either a Double Pedalo with handles (simple task) or without handles (complex task) over a distance of 7 meters. A Double Pedalo is a four-wheeled device that involves standing on two connected platforms, and alternately pushing them forward to make it move. Participants completed 20 acquisition trials, followed by a 24-hour retention test. For the simpler task, no time differences due to attentional focus emerged. With the complex task, an external focus resulted in faster times in retention than an internal focus, but only for males. These findings suggest that attentional focus affects children and adults similarly, but task complexity and sex moderate these effects.

    Vakrman, Tomas; Kristoufek, Ladislav

    2015-01-01

    Online activity of Internet users has proven very useful in modeling various phenomena across a wide range of scientific disciplines. In our study, we focus on two stylized facts or puzzles surrounding the initial public offerings (IPOs) - the underpricing and the long-term underperformance. Using the Internet searches on Google, we proxy the investor attention before and during the day of the offering to show that the high attention IPOs have different characteristics than the low attention ones. After controlling for various effects, we show that investor attention still remains a strong component of the high initial returns (the underpricing), primarily for the high sentiment periods. Moreover, we demonstrate that the investor attention partially explains the overoptimistic market reaction and thus also a part of the long-term underperformance.

    2015-12-01

    [Purpose] The present study reviewed studies that examined the effects of attentional focus on balance. [Methods] Keywords such as "attentional", "focus", and "balance" were used to find relevant research papers in PubMed (www.ncbi.nlm.nih.gov/pubmed). Forty-five papers were found, and 18 of them were used for this study, excluding review papers and papers irrelevant to the topic of this study. [Results] Among the papers used for the review, the number of papers in which external focus produced effective outcomes was 15 (83.3%). The number of papers in which both external and internal focus produced effective outcomes was 2 (11.1%). The number of paper in which no instruction about attentional focus was effective was 1 (5.5%), and the number of papers in which internal focus was effective was zero. [Conclusion] This short review suggests clinical implications about how physical therapists can use attentional focus for balance rehabilitation of patients. Instructions about external focus of attention can generally be useful as a method to improve posture and balance control. Furthermore, the present reviews indicates that external focus of attention would be more useful in a rehabilitation stage in which the difficulty level of balance performance is gradually increased.

    2014-04-01

    The distribution of visual attention has been the topic of much investigation, and various theories have posited that attention is allocated either as a single unitary focus or as multiple independent foci. In the present experiment, we demonstrate that attention can be flexibly deployed as either a unitary or a divided focus in the same experimental task, depending on the observer's goals. To assess the distribution of attention, we used a dual-stream Attentional Blink (AB) paradigm and 2 target pairs. One component of the AB, Lag-1 sparing, occurs only if the second target pair appears within the focus of attention. By varying whether the first-target-pair could be expected in a predictable location (always in-stream) or not (unpredictably in-stream or between-streams), observers were encouraged to deploy a divided or a unitary focus, respectively. When the second-target-pair appeared between the streams, Lag-1 sparing occurred for the Unpredictable group (consistent with a unitary focus) but not for the Predictable group (consistent with a divided focus). Thus, diametrically different outcomes occurred for physically identical displays, depending on the expectations of the observer about where spatial attention would be required.

  16. Multiperson visual focus of attention from head pose and meeting contextual cues.

    Ba, Sileye O; Odobez, Jean-Marc

    2011-01-01

    This paper introduces a novel contextual model for the recognition of people's visual focus of attention (VFOA) in meetings from audio-visual perceptual cues. More specifically, instead of independently recognizing the VFOA of each meeting participant from his own head pose, we propose to jointly recognize the participants' visual attention in order to introduce context-dependent interaction models that relate to group activity and the social dynamics of communication. Meeting contextual information is represented by the location of people, conversational events identifying floor holding patterns, and a presentation activity variable. By modeling the interactions between the different contexts and their combined and sometimes contradictory impact on the gazing behavior, our model allows us to handle VFOA recognition in difficult task-based meetings involving artifacts, presentations, and moving people. We validated our model through rigorous evaluation on a publicly available and challenging data set of 12 real meetings (5 hours of data). The results demonstrated that the integration of the presentation and conversation dynamical context using our model can lead to significant performance improvements.

    In our research we examined the relation between creative and analytical thinking. We also tried to determine the relation of both types of thinking with divided and sustained attention. Some authors believe that creative and analytical thinking are in contradiction with each other. There is also a question of connection of both types of thinking with attention. Analytical thinking is supposed to be connected with focused attention, while creative thinking is suppose to connect with divided a...

    It is widely assumed that the short-term retention of information is accomplished via maintenance of an active neural trace. However, we demonstrate that memory can be preserved across a brief delay despite the apparent loss of sustained representations. Delay-period activity may in fact reflect the focus of attention, rather than short-term memory. We unconfounded attention and memory by causing external and internal shifts of attention away from items that were being actively retained. Mult...

    2010-01-01

    This study examined the effects of state self-focused attention on sexual arousal and trait self-consciousness on sexual arousal and function in sexually functional (n = 16) and dysfunctional (n = 16) women. Self-focused attention was induced using a 50% reflectant television screen in one of two counterbalanced sessions during which self-report and physiological sexual responses to erotic films were measured. Self-focused attention significantly decreased vaginal pulse amplitude (VPA) responses among sexually functional but not dysfunctional women, and substantially decreased correlations between self-report and VPA measures of sexual arousal. Self-focused attention did not significantly impact subjective sexual arousal in sexually functional or dysfunctional women. Trait private self-consciousness was positively related to sexual desire, orgasm, compatibility, contentment and sexual satisfaction. Public self-consciousness was correlated with sexual pain. The findings are discussed in terms of Masters and Johnson’s [Masters, W. H. & Johnson, V. E. (1970). Human sexual inadequacy. Boston: Little, Brown) concepts of “spectatoring” and “sensate focus.” PMID:15927143

    Full Text Available Background: Great importance has been given in recent years to the impact of focus of attention cues during skills execution but not during real game play, where more cognitive skills are involved besides technical performance. Objective: The purpose of the present study was to examine the effect of internal and external focus of attention instructions on the components of the game performance (decision making, skill execution, base in tennis. Methods: The participants (N = 60 were divided into three groups and followed an intervention training program that lasted 6 weeks; IF group (n = 20 under internal focus of attention instructions, EF group (n = 20 under external focus of attention instructions and CON group (n = 20 under no attentional focus instructions. Three measurements took place (pre, post and ret in which the participants were recorded on video while playing matches in real scoring conditions. Game Performance Assessment Instrument (GPAI was used to evaluate the components of game performance in tennis in three game situations; service, return of the service, base line game. Results: ANOVA repeated measures in a 3 (groups: IF, EF & CON × 3 (measurements: pre, post, ret revealed a significant interaction between groups and measurements and post hoc analysis indicated that the group that was instructed to focus externally improved significantly only in decision making compared to the internal focus of attention and to the control group. The score difference was maintained at the retention test as well, which indicates that the impact concerned not only performance but also learning. Conclusions: Instructions that aim to an external focus of attention enhance decision making skills, which are considered the most important element of game performance in tennis.

    Motor performance in familiar tasks is often advantaged when performers focus on the effects of their movements rather than on the movements themselves. But, this phenomenon has yet to be studied systematically in the context of vocal production. I evaluated 20 trained singers' vocal tone as they varied their focus of attention. Each participant…

    Rehabilitation for patients with Parkinson’s disease (PD) is based on cognitive strategies that exploit attention. Parkinsonians exhibit impairments in divided attention and interference control. Nevertheless, the effectiveness of specific rehabilitation treatments based on attention suggests that other attentional functions are preserved. Data about attention are conflicting in PD, and it is not clear whether rehabilitative treatments that entail attentional strategies affect attention itself. Reaction times (RTs) represent an instrument to explore attention and investigate whether changes in attentional performances parallel rehabilitation induced-gains. RTs of 103 parkinsonian patients in “on” state, without cognitive deficits, were compared with those of a population of 34 healthy controls. We studied those attentional networks that subtend the use of cognitive strategies in motor rehabilitation: alertness and focused and sustained attention, which is a component of the executive system. We used visual and auditory RTs to evaluate alertness and multiple choices RTs (MC RTs) to explore focused and sustained attention. Parkinsonian patients underwent these tasks before and after a 4-week multidisciplinary, intensive and goal-based rehabilitation treatment (MIRT). Unified Parkinson’s Disease Rating Scale (UPDRS) III and Timed Up and Go test (TUG) were assessed at the enrollment and at the end of MIRT to evaluate the motor-functional effectiveness of treatment. We did not find differences in RTs between parkinsonian patients and controls. Further, we found that improvements in motor-functional outcome measures after MIRT (p analysis revealed no association between changes in MC RTs and improvements in UPDRS-III and TUG. These findings indicate that alertness, as well as focused and sustained attention, are preserved in “on” state. This explains why Parkinsonians benefit from a goal-based rehabilitation that entails the use of attention. The reduction in

    Meditation is becoming increasingly popular as a topic for scientific research and theories on meditation are becoming ever more specific. We distinguish between what is called focused Attention meditation, open Monitoring meditation, and loving kindness (or compassion) meditation. Research suggests that these meditations have differential, dissociable effects on a wide range of cognitive (control) processes, such as attentional selection, conflict monitoring, divergent, and convergent thinking. Although research on exactly how the various meditations operate on these processes is still missing, different kinds of meditations are associated with different neural structures and different patterns of electroencephalographic activity. In this review we discuss recent findings on meditation and suggest how the different meditations may affect cognitive processes, and we give suggestions for directions of future research.

    Objective self-awareness theory contends that focusing attention on the self initiates an automatic comparison of self to standards. To gain evidence for automatic self-standard comparison processes, two experiments manipulated attention to self with subliminal first-name priming. People completed a computer-based parity task after being instructed that the standard was to be fast or to be accurate. Subliminal first name priming increased behavioral adherence to the explicit standard. When told to be fast, self-focused people made more mistakes and had faster response times; when told to be accurate, self-focused people made fewer mistakes. A manipulation of conscious self-awareness (via a mirror) had the same self-regulatory effects. The findings suggest that comparing self to standards can occur automatically and that it is attention to self, not awareness of the self per se, that evokes self-evaluation.

    Third-party altruistic decision-making has been shown to be modulated by other-regarding attention (e.g., focusing on the offender’s crime or the victim’s situation especially in judicial judgment). However, the neural mechanisms underlying this modulation remain poorly understood. In this fMRI study, participants voluntarily decided if they wanted to punish the first-party offender or help the second-party victim using their own monetary endowment in an unfair context. Particularly, before deciding they were asked to focus on the (un)fairness of the offender proposing the offer (offender-focused block, OB), the feeling of the victim receiving this offer (victim-focused block, VB), or without any specific focus (baseline block, BB). We found that compared to BB participants punished more frequently and prolonged help choices in OB, whereas they helped more frequently in VB. These findings were accompanied by an increased activation in the temporo-parietal junction (TPJ) during decision making in OB and VB. Moreover, regions relevant to cognitive control (esp. IFG/AI and the dorsal anterior cingulate cortex) were strongly recruited during specific choices conflicting the attention focus (e.g., choosing help in OB). Our findings revealed how other-regarding attention modulates third-party altruistic decision-making at the neural level. PMID:28220867

    Judah, Matt R; Grant, DeMond M; Carlisle, Nancy B

    2016-06-01

    Cognitive theories of social anxiety disorder suggest that biased attention plays a key role in maintaining symptoms. These biases include self-focus and attention to socially threatening stimuli in the environment. The goal of this study was to utilize ERPs that are elicited by a change detection task to examine biases in selective attention (i.e., N2pc) and working memory maintenance (i.e., contralateral delay activity; CDA). Additionally, the effect of self-focus was examined using false heart rate feedback. In support of the manipulation, self-focus cues resulted in greater self-reported self-consciousness and task interference, enhanced anterior P2 amplitude and reduced SPN amplitude. Moreover, P2 amplitude for self-focus cues was correlated with reduced task performance for socially anxious subjects only. The difference in P2 amplitude between self-focus and standard cues was correlated with social anxiety independent of depression. As hypothesized, socially anxious participants (n = 20) showed early selection and maintenance of disgust faces relative to neutral faces as indicated by the N2pc and CDA components. Nonanxious controls (n = 22) did not show these biases. During self-focus cues, controls showed marginal evidence of biased selection for disgust faces, whereas socially anxious subjects showed no bias in this condition. Controls showed an ipsilateral delay activity after being cued to attend to one hemifield. Overall, this study supports early and persistent attentional bias for social threat in socially anxious individuals. Furthermore, self-focus may disrupt these biases. These findings and supplementary data are discussed in light of cognitive models of social anxiety disorder, recent empirical findings, and treatment.

  19. Meditation Breath Attention Scores (MBAS): Development and investigation of an internet-based assessment of focused attention during meditation practice.

    Meditation Breath Attention Scores (MBAS) represent a self-report, state measure of focused attention (FA) during the practice of meditation. The MBAS assessment procedure involves sounding a bell at periodic intervals during meditation practice, at which times participants indicate if they were attending toward breathing (scored 1) or if instead they had become distracted (e.g., by mind wandering; scored 0); scores are then tallied to yield participants' MBAS for that meditation. The current study developed and evaluated a fully automated and Internet-based version of MBAS in 1,101 volunteers. Results suggested that: (a) MBAS are internally consistent across bell rings; (b) MBAS total scores exhibit a non-normal distribution identifying subgroups of participants with particularly poor or robust FA during meditation; (c) MBAS decrease linearly with the duration of meditation practices, indicating that participants tend to experience less FA later as opposed to earlier in the meditation; (d) in the case of eyes-open meditation, MBAS are higher when the amount of time between bells is shorter; (e) MBAS correlate with various self-reported subjective experiences occurring during meditation; and (f) MBAS are weakly associated with higher trait mindful "acting with awareness," lesser ADHD-related symptoms of inattentiveness, and estimated minutes of meditation practiced in the past month. In sum, results provide further support for the construct validity of MBAS and serve to further characterize the dynamics of individual differences in FA during meditation.

    The present study was designed to fill a gap in the literature on attentional focus and sports performance. Specifically, in contrast to most previous studies in which an external focus was directed at an implement, we used a gymnastics skill that did not involve the use of an implement. Furthermore, while most studies used only outcome measures of performance, we also assessed movement quality. Twelve-year-old gymnasts performed a maximum vertical jump with a 180-degree turn while airborne, with their hands crossing in front of their chest during the turn under three different focus conditions. Under the external focus condition, participants were asked to focus on the direction in which a tape marker, which was attached to their chest, was pointing after the turn. Under the internal focus condition, they were asked to focus on the direction in which their hands were pointing after the turn. Under the control condition, no focus instructions were given. The external focus condition resulted in both superior movement form and greater jump height than did the other two conditions, which produced comparable results. The present findings show that, similar to other tasks, the performance of form-based skills can be enhanced relatively easily by appropriate external focus instructions.

    Over the last 30 years, researchers have disagreed over the consequences of diverting attention from threat for exposure efficacy, which is an important theoretical and clinical debate. Therefore, the present meta-analysis assessed the efficacy of attentionally focused exposure against distracted and attentionally uninstructed exposure regarding distress, behavioral, and physiological outcomes. We included 15 randomized studies with specific phobia, totaling 444 participants and targeting outcomes at post-exposure and follow-up. Results indicated no difference between the efficacy of distracted exposure as opposed to focused or uninstructed exposure for distress and physiology. For behavior, at post-exposure, results were marginally significant in favor of distracted as opposed to focused exposure, while at follow-up results significantly favored distraction. However, concerning behavior, uninstructed exposure was superior to distraction. Moderation analyses revealed that, regarding distress reduction and approach behavior, distracted exposure significantly outperformed focused exposure when the distracter was interactive (g=1.010/g=1.128) and exposure was spread over the course of multiple sessions (g=1.527/g=1.606). No moderation analysis was significant for physiological measures. These findings suggest that distraction during exposure could be less counterproductive than previously considered and even beneficial under certain circumstances. Theoretical implications and future directions for research are discussed.

    2013-01-01

    Full Text Available The present study investigated the enhancement effects of an external focus-of-attention (FOA in the context of a manual-tracking task, in which participants tracked both visible and occluded targets. Three conditions were compared, which manipulated the distance of the FOA from the participant as well as the external/internal dimension. As expected, an external FOA resulted in lower tracking errors than an internal FOA. In addition, analyses of participants' movement patterns revealed a systematic shift toward higher-frequency movements in the external FOA condition, consistent with the idea that an external FOA exploits the natural movement dynamics available during skilled action. Finally, target visibility did not influence the effect of focused attention on tracking performance, which provides evidence for the proposal that the mechanisms that underlie FOA do not depend directly on vision.

    In order to explore the neurobiological foundations of qualitative subjective experiences, the present study was designed to correlate objective third-person brain fMRI measures with subjective first-person identification and scaling of local, subtle, and specific somatosensory sensations, obtained directly after the imaging procedure. Thus, thirty-four volunteers were instructed to focus and sustain their attention to either provoked or spontaneous sensations of each thumb during the fMRI procedure. By means of a Likert scale applied immediately afterwards, the participants recalled and evaluated the intensity of their attention and identified specific somatosensory sensations (e.g. pulsation, vibration, heat). Using the subject's subjective scores as covariates to model both attention intensity and general somatosensory experiences regressors, the whole-brain random effect analyses revealed activations in the frontopolar prefrontal cortex (BA10), primary somatosensory cortex (BA1), premotor cortex (BA 6), precuneus (BA 7), temporopolar cortex (BA 38), inferior parietal lobe (BA 39), hippocampus, insula and amygdala. Furthermore, BA10 showed differential activity, with ventral BA10 correlating exclusively with attention (r(32) = 0.54, p = 0.0013) and dorsal BA10 correlating exclusively with somatosensory sensation (r(32) = 0.46, p = 0.007). All other reported brain areas showed significant positive correlations solely with subjective somatosensory experiences reports. These results provide evidence that the frontopolar prefrontal cortex has dissociable functions depending on specific cognitive demands; i.e. the dorsal portion of the frontopolar prefrontal cortex in conjunction with primary somatosensory cortex, temporopolar cortex, inferior parietal lobe, hippocampus, insula and amygdala are involved in the processing of spontaneous general subjective somatosensory experiences disclosed by focused and sustained attention.

    In the OPTIMAL theory of motor learning [Wulf, G., & Lewthwaite, R. (2016). Optimizing performance through intrinsic motivation and attention for learning: The OPTIMAL theory of motor learning. Psychonomic Bulletin & Review. doi:10.3758/s13423-015-0999-9], 3 factors are postulated to facilitate learning: enhanced expectancies (EE) for performance, autonomy support (AS), and an external focus (EF) of attention. In 3 recent studies, combinations 2 of these variables resulted in superior learning relative to the presence of only 1 variable, or none. We examined whether the combination of all 3 factors would enhance learning relative to combinations of 2 factors. Our design included EE-AS, EE-EF, AS-EF, and AS-EE-EF groups. Participants threw balls at a target with their non-dominant arm. In the EE conditions, they received positive social-comparative feedback. In the AS conditions, they were allowed to throw with their dominant arm on trial blocks chosen by them. In the EF conditions, participants were asked to focus on the target. On a delayed retention test, the AS-EE-EF group outperformed all other groups. The findings provide evidence that enhanced expectancies, autonomy support, and an external focus can contribute in an additive fashion to optimize motor learning.

Twenty-two male Chinese expert meditators (11 FAM experts, 11 LKM experts and 22 male Chinese novice meditators (11 FAM novices, 11 LKM novices had their brain activity monitored by a 3T MRI scanner while performing the cognitive and affective tasks in both meditation and baseline states. We examined the interaction between state (meditation vs. baseline and expertise (expert vs. novice separately during LKM and FAM, using a conjunction approach to reveal common regions sensitive to the expert meditative state. Additionally, exclusive masking techniques revealed distinct interactions between state and group during LKM and FAM. Specifically, we demonstrated that the practice of FAM was associated with expertise-related behavioral improvements and neural activation differences in attention task performance. However, the effect of state LKM meditation did not carry over to attention task performance. On the other hand, both FAM and LKM practice appeared to affect the neural responses to affective pictures. For viewing sad faces, the regions activated for FAM practitioners were consistent with attention-related processing; whereas responses of LKM experts to sad pictures were more in line with differentiating emotional contagion from compassion/emotional regulation processes. Our findings provide the first report of distinct neural activity associated with forms of meditation during sustained attention and emotion processing.

    This study examined the dissociable neural effects of ānāpānasati (focused-attention meditation, FAM) and mettā (loving-kindness meditation, LKM) on BOLD signals during cognitive (continuous performance test, CPT) and affective (emotion-processing task, EPT, in which participants viewed affective pictures) processing. Twenty-two male Chinese expert meditators (11 FAM experts, 11 LKM experts) and 22 male Chinese novice meditators (11 FAM novices, 11 LKM novices) had their brain activity monitored by a 3T MRI scanner while performing the cognitive and affective tasks in both meditation and baseline states. We examined the interaction between state (meditation vs. baseline) and expertise (expert vs. novice) separately during LKM and FAM, using a conjunction approach to reveal common regions sensitive to the expert meditative state. Additionally, exclusive masking techniques revealed distinct interactions between state and group during LKM and FAM. Specifically, we demonstrated that the practice of FAM was associated with expertise-related behavioral improvements and neural activation differences in attention task performance. However, the effect of state LKM meditation did not carry over to attention task performance. On the other hand, both FAM and LKM practice appeared to affect the neural responses to affective pictures. For viewing sad faces, the regions activated for FAM practitioners were consistent with attention-related processing; whereas responses of LKM experts to sad pictures were more in line with differentiating emotional contagion from compassion/emotional regulation processes. Our findings provide the first report of distinct neural activity associated with forms of meditation during sustained attention and emotion processing.

    Background A person is less likely to be accurately remembered if they appear in a visual scene with a gun, a result that has been termed the weapon focus effect (WFE). Explanations of the WFE argue that weapons engage attention because they are unusual and/or threatening, which causes encoding deficits for the other items in the visual scene. Previous WFE research has always embedded the weapon and nonweapon objects within a larger context that provides information about an actor's intention to use the object. As such, it is currently unknown whether a gun automatically engages attention to a greater extent than other objects independent of the context in which it is presented. Method Reflexive responding to a gun compared to other objects was examined in two experiments. Experiment 1 employed a prosaccade gap-overlap paradigm, whereby participants looked toward a peripheral target, and Experiment 2 employed an antisaccade gap-overlap paradigm, whereby participants looked away from a peripheral target. In both experiments, the peripheral target was a gun or a nonthreatening object (i.e., a tomato or pocket watch). We also controlled how unexpected the targets were and compared saccadic reaction times across types of objects. Results A gun was not found to differentially engage attention compared to the unexpected object (i.e., a pocket watch). Some evidence was found (Experiment 2) that both the gun and the unexpected object engaged attention to a greater extent compared the expected object (i.e., a tomato). Conclusion An image of a gun did not engage attention to a larger extent than images of other types of objects (i.e., a pocket watch or tomato). The results suggest that context may be an important determinant of WFE. The extent to which an object is threatening may depend on the larger context in which it is presented. PMID:24349028

    When a test of working memory (WM) requires the retention of multiple items, a subset of them can be prioritized. Recent studies have shown that, although prioritized (i.e., attended) items are associated with active neural representations, unprioritized (i.e., unattended) memory items can be retained in WM despite the absence of such active representations, and with no decrement in their recognition if they are cued later in the trial. These findings raise two intriguing questions about the nature of the short-term retention of information outside the focus of attention. First, when the focus of attention shifts from items in WM, is there a loss of fidelity for those unattended memory items? Second, could the retention of unattended memory items be accomplished by long-term memory mechanisms? We addressed the first question by comparing the precision of recall of attended versus unattended memory items, and found a significant decrease in precision for unattended memory items, reflecting a degradation in the quality of those representations. We addressed the second question by asking subjects to perform a WM task, followed by a surprise memory test for the items that they had seen in the WM task. Long-term memory for unattended memory items from the WM task was not better than memory for items that had remained selected by the focus of attention in the WM task. These results show that unattended WM representations are degraded in quality and are not preferentially represented in long-term memory, as compared to attended memory items.

    This study examined the relationship between focused attention meditation practice habits, psychological symptoms, and quality of life. The participants were 30 adults from New York, NY, practicing Ananda Marga spirituality. They were administered the Symptom Check List-90-R and the Quality of Life Index. The findings pointed out while Ananda Marga meditation practice habits were not associated with improvements in psychological symptoms, longer years in meditation practice was associated with improvements in overall, social and psychological/spiritual quality of life. Longer periods of meditation practice per session were related to lower levels of overall quality of life and economic quality of life.

    Anecdotes from creative eminences suggest that executive control plays an important role in creativity, but scientific evidence is sparse. Invoking the Dual Pathway to Creativity Model, the authors hypothesize that working memory capacity (WMC) relates to creative performance because it enables persistent, focused, and systematic combining of elements and possibilities (persistence). Study 1 indeed showed that under cognitive load, participants performed worse on a creative insight task. Study 2 revealed positive associations between time-on-task and creativity among individuals high but not low in WMC, even after controlling for general intelligence. Study 3 revealed that across trials, semiprofessional cellists performed increasingly more creative improvisations when they had high rather than low WMC. Study 4 showed that WMC predicts original ideation because it allows persistent (rather than flexible) processing. The authors conclude that WMC benefits creativity because it enables the individual to maintain attention focused on the task and prevents undesirable mind wandering.

  18. Examining the Relative Contribution of Memory Updating, Attention Focus Switching, and Sustained Attention to Children’s Verbal Working Memory Span

    Full Text Available Whereas considerable developmental memory research has examined the contributions of short-term memory, processing efficiency, retention duration, and scope of attention to complex memory span, little is known about the influence of controlled attention. The present study investigated the relative influence of three understudied attention mechanisms on the verbal working memory span of school-age children: memory updating; attention focus switching; and sustained attention. Results of general linear modeling revealed that, after controlling for age, only updating accuracy emerged as a significant predictor of verbal working memory span. Memory updating speed (that subsumed attention focus switching speed also contributed but was mediated by age. The results extend the developmental memory literature by implicating the mechanism of memory updating and developmental improvement in speed of attention focus switching and updating as critical contributors to children’s verbal working memory. Theoretically, the results provide substantively new information about the role of domain-general executive attention in children’s verbal working memory.

    The pupillary light response is often assumed to be a reflex that is not susceptible to cognitive influences. In line with recent converging evidence, we show that this reflexive view is incomplete, and that the pupillary light response is modulated by covert visual attention: Covertly attending to a bright area causes a pupillary constriction, relative to attending to a dark area under identical visual input. This attention-related modulation of the pupillary light response predicts cuing effects in behavior, and can be used as an index of how strongly participants attend to a particular location. Therefore, we suggest that pupil size may offer a new way to continuously track the focus of covert visual attention, without requiring a manual response from the participant. The theoretical implication of this finding is that the pupillary light response is neither fully reflexive, nor under complete voluntary control, but is instead best characterized as a stereotyped response to a voluntarily selected target. In this sense, the pupillary light response is similar to saccadic and smooth pursuit eye movements. Together, eye movements and the pupillary light response maximize visual acuity, stabilize visual input, and selectively filter visual information as it enters the eye.

  4. Three-dimensional focus of attention for iterative cone-beam micro-CT reconstruction

    Three-dimensional iterative reconstruction of high-resolution, circular orbit cone-beam x-ray CT data is often considered impractical due to the demand for vast amounts of computer cycles and associated memory. In this paper, we show that the computational burden can be reduced by limiting the reconstruction to a small, well-defined portion of the image volume. We first discuss using the support region defined by the set of voxels covered by all of the projection views. We then present a data-driven preprocessing technique called focus of attention that heuristically separates both image and projection data into object and background before reconstruction, thereby further reducing the reconstruction region of interest. We present experimental results for both methods based on mouse data and a parallelized implementation of the SIRT algorithm. The computational savings associated with the support region are substantial. However, the results for focus of attention are even more impressive in that only about one quarter of the computer cycles and memory are needed compared with reconstruction of the entire image volume. The image quality is not compromised by either method.

  5. Learning a new bimanual coordination pattern: interlimb interactions, attentional focus, and transfer.

    Because bimanual coordinative stability is governed by interlimb coupling, we examined how learning a new pattern (90°) was reflected in changes in the underlying interlimb interactions. Three interlimb interaction sources were distinguished: integrated timing of feedforward control signals, error corrections based on perceived relative phase, and phase entrainment by contralateral afference. By comparing 4 tasks that involve these interactions to a different extent, changes in the stabilizing contributions of these coupling sources could be studied. Furthermore, we studied how the learning process and changes in the underlying interactions were influenced by attentional focus (internal vs. external), and we examined retention of the learned pattern and transfer to the mirror-symmetrical pattern (270°). Results showed that stability and accuracy of the new pattern increased significantly with learning, due to improved integrated timing and error correction. Integrated timing improved first, possibly providing a reference frame for the error corrections that subsequently became more effective. Despite some qualitative differences in the learning process, neither performance of the learned pattern nor the underlying interlimb interactions was influenced by attentional focus. Whereas the learned pattern improved directly after practice, transfer followed later, suggesting that a more general representation was formed at a slower rate after practice.

  6. Default mode network activation and Transcendental Meditation practice: Focused Attention or Automatic Self-transcending?

    This study used subjective reports and eLORETA analysis to assess to what extent Transcendental Meditation (TM) might involve focused attention-voluntary control of mental content. Eighty-seven TM subjects with one month to five years TM experience participated in this study. Regression analysis of years TM practice and self-reported transcendental experiences (lack of time, space and body sense) during meditation practice was flat (r=.07). Those practicing Transcendental Meditation for 1month reported as much transcending as those with 5years of practice. The eLORETA comparison of eyes-closed rest/task and TM practice/task identified similar areas of activation: theta and alpha activation during rest and TM in the posterior cingulate and precuneus, part of the default mode network, and beta2 and beta3 activation during the task in anterior cingulate, ventral lateral and dorsolateral prefrontal cortices, part of the central executive network. In addition, eLORETA comparison of rest and TM identified higher beta temporal activation during rest and higher theta orbitofrontal activation during TM. Thus, it does not seem accurate to include TM practice with meditations in the catgory of Focused Attention, which are characterized by gamma EEG and DMN deactivation. Mixing meditations with different procedures into a single study confounds exploration of meditation effects and confounds application of meditation practices to different subject populations.

    What determines government attention to emerging health issues? We draw on research in agenda setting and policy diffusion to explore the determinants of public health attention in the fifty American states. We find that intergovernmental influence has a strong and consistent influence over state attention to tobacco and vaccines from 1990 to 2010. While national attention to tobacco or vaccines also sparks attention in the states, this effect is smaller than the internal impact of gubernatorial attention and the horizontal influence of neighboring state attention. We find some support that problem severity matters; however, these results are highly dependent on the measures used. Finally, we find no evidence that interest groups influence the attention that states pay to tobacco or vaccines. Our results suggest that institutions play a critical role in explaining government attention to health policy.

    The present study is aimed to diagnose the current public programs focused on herbal medicines in Brazil by means of in loco visits to 10 programs selected by means of questionnaires sent to 124 municipalities that count on herbal medicine services. The main purpose of the implementation of program programs is related to the development of medicinal herbs. 70% of them are intended for the production of herbal medicines and 50% are aimed to ensure the access of the population to medicinal plants and or herbal medicines. The initiative of the implementation of these programs was related to the managers (60%). The difficulties in this implementation were due to the lack of funding (100%) of the programs. In 60% of the programs, the physicians did not adhere to herbal medicine services due to the lack of knowledge of the subject. Training courses were proposed (80%) to increase the adhesion of prescribers to the system. Some municipalities use information obtained from patients to assess the therapeutic efficiency of medicinal plants and herbal medicines. Of the programs underway, cultivation of medicinal plants was observed in 90% and 78% of them adopt quality control. In most programs, this control is not performed in accordance with the legal requirements. The programs focused on medicinal plants and herbal medicines implemented in Brazil face some chronic problems of infrastructure, management, operational capacity and self-sustainability, which can be directly related to the absence of a national policy on medicinal plants and herbal medicines.

  9. Evidence inhibition responds reactively to the salience of distracting information during focused attention.

    Directory of Open Access Journals (Sweden)

    Natalie Wyatt

    Full Text Available Along with target amplification, distractor inhibition is regarded as a major contributor to selective attention. Some theories suggest that the strength of inhibitory processing is proportional to the salience of the distractor (i.e., inhibition reacts to the distractor intensity. Other theories suggest that the strength of inhibitory processing does not depend on the salience of the distractor (i.e., inhibition does not react to the distractor intensity. The present study aimed to elucidate the relationship between the intensity of a distractor and its subsequent inhibition during focused attention. A flanker task with a variable distractor-target stimulus-onset asynchrony (SOA was used to measure both distractor interference and distractor inhibition. We manipulated the intensity of the distractor in two separate ways, by varying its distance from the target (Experiment 1 and by varying its brightness (Experiment 2. The results indicate that more intense distractors were associated with both increased interference and stronger distractor inhibition. The latter outcome provides novel support for the reactive inhibition hypothesis, which posits that inhibition reacts to the strength of distractor input, such that more salient distractors elicit stronger inhibition.

    Humans often must coordinate co-occurring activities, and their flexible skills for doing so would seem to be uniquely powerful. In 2 studies, we compared 4- and 5-year-old children and one of humans' nearest relatives, chimpanzees, in their ability to focus and shift their attention when necessary. The results of Study 1 showed that 4-year-old children and chimpanzees were very similar in their ability to monitor two identical devices and to sequentially switch between the two to collect a reward, and that they were less successful at doing so than 5-year-old children. In Study 2, which required subjects to alternate between two different tasks, one of which had rewards continuously available whereas the other one only occasionally released rewards, no species differences were found. These results suggest that chimpanzees and human children share some fundamental attentional control skills, but that such abilities continue to develop during human ontogeny, resulting in the uniquely human capacity to succeed at complex multitasking.

    Full Text Available Kawaii (a Japanese word meaning "cute" things are popular because they produce positive feelings. However, their effect on behavior remains unclear.

In the first experiment, university students performed a fine motor dexterity task before and after viewing images of baby or adult animals. Performance indexed by the number of successful trials increased after viewing cute images (puppies and kittens; M ± SE=43.9 ± 10.3% improvement more than after viewing images that were less cute (dogs and cats; 11.9 ± 5.5% improvement. In the second experiment, this finding was replicated by using a non-motor visual search task. Performance improved more after viewing cute images (15.7 ± 2.2% improvement than after viewing less cute images (1.4 ± 2.1% improvement. Viewing images of pleasant foods was ineffective in improving performance (1.2 ± 2.1%. In the third experiment, participants performed a global-local letter task after viewing images of baby animals, adult animals, and neutral objects. In general, global features were processed faster than local features. However, this global precedence effect was reduced after viewing cute images. Results show that participants performed tasks requiring focused attention more carefully after viewing cute images. This is interpreted as the result of a narrowed attentional focus induced by the cuteness-triggered positive emotion that is associated with approach motivation and the tendency toward systematic processing. For future applications, cute objects may be used as an emotion elicitor to induce careful behavioral tendencies in specific situations, such as driving and office work.

    Speech perception under complex listening conditions usually decreases in aging. This is especially true for listening conditions requiring divided attention among 2 and more relevant speakers. Using a speech perception task and event-related potential measures, we studied the ability of younger and older adults to attend to speech information from a single-target speaker (focused attention) or from 2 different (alternative) target speakers (divided attention). The focused and divided attention conditions were presented either in silence or in the presence of 3 concurrent speakers. In the presence of concurrent speakers, older participants showed worse performance with divided versus focused attention. In contrast, there was no effect of attention condition for the younger adults. Relative to the young, event-related potential analysis in older subjects indicated a decline in preparatory activity for the critical speech information (a delayed and smaller contingent negative variation), and delayed attentional control (indicated by a longer P2 latency). Standardized low-resolution brain electromagnetic tomography revealed that the age-related decline in preparatory activity was associated with reduced activation of medial and superior frontal gyrus and anterior cingulate gyrus. The results suggest that age-related differences in these prefrontal brain areas reflect declines in preparatory attention and gating of subsequent task-related speech information, especially under conditions of divided attention. These findings may reflect mechanisms relating to impaired speech perception by older people in "cocktail-party" listening situations.

    This study investigated the functional significance of EEG alpha power increases, a finding that is consistently observed in various memory tasks and specifically during divergent thinking. It was previously shown that alpha power is increased when tasks are performed in mind-e.g., when bottom-up processing is prevented. This study aimed to examine the effect of task-immanent differences in bottom-up processing demands by comparing two divergent thinking tasks, one intrinsically relying on bottom-up processing (sensory-intake task) and one that is not (sensory-independence task). In both tasks, stimuli were masked in half of the trials to establish conditions of higher and lower internal processing demands. In line with the hypotheses, internal processing affected performance and led to increases in alpha power only in the sensory-intake task, whereas the sensory-independence task showed high levels of task-related alpha power in both conditions. Interestingly, conditions involving focused internal attention showed a clear lateralization with higher alpha power in parietal regions of the right hemisphere. Considering evidence from fMRI studies, right-parietal alpha power increases may correspond to a deactivation of the right temporoparietal junction, reflecting an inhibition of the ventral attention network. Inhibition of this region is thought to prevent reorienting to irrelevant stimulation during goal-driven, top-down behavior, which may serve the executive function of task shielding during demanding cognitive tasks such as idea generation and mental imagery.

    According to Barlow's model of sexual dysfunction, anxiety in sexual situations leads to attentional focus on sexual performance at the expense of erotic cues, which compromises sexual arousal. This negative experience will enhance anxiety in future sexual situations, and non-erotic thoughts (NETs) relevant to performance will receive attentional priority. Previous research with student samples (Purdon & Holdaway, 2006; Purdon & Watson, 2010) has found that people experience many types of NETs in addition to performance-relevant thoughts, and that, consistent with Barlow's model, the frequency of and anxiety evoked by these thoughts is positively associated with sexual problems. Extending this previous work, the current study found that, in a community sample of women (N = 81) and men (N = 72) in long-term relationships, women were more likely to report body image concerns and external consequences of the sexual activity, while men were more likely to report performance-related concerns. Equally likely among men and women were thoughts about emotional consequences of the sexual activity. Regardless of thought content, experiencing more frequent NETs was associated with more sexual problems in both women and men. Moreover, as per Barlow's model, greater negative affect in anticipation of and during sexual activity predicted greater frequency of NETs and greater anxiety in response to NETs was associated with greater difficulty dismissing the thoughts. However, greater difficulty in refocusing on erotic thoughts during sexual activity uniquely predicted more sexual problems above the frequency and dismissability of NETs. Together, these data support the cognitive interference mechanism implicated by Barlow's causal model of sexual dysfunction and have implications for the treatment of sexual problems.

    In the 2010 National Research Council’s America’s Climate Choices’ report on Informing Effective Decisions and Actions Related to Climate Change concluded; “Education and communication are among the most powerful tools the nation has to bring hidden hazards to public attention, understanding, and action.” They conclude that the “current and future students, the broader public, and policymakers need to understand the causes, consequences, and potential solutions to climate change, develop scientific thinking and problem-solving skills, and improve their ability to make informed decisions.” The U.S. Global Change Research Program (USGCRP) works to integrate the climate related activities of these different agencies, with oversight from the Office of Science and Technology Policy and other White House offices. USGCRP’s focus is now on evaluating optimal strategies for addressing climate change risks, improving coordination among the Federal agencies, engaging stakeholders (including national policy leaders and local resource managers) on the research results to all and improving public understanding and decision-making related to global change. Implicit to these activities is the need to educate the public about the science of climate change and its consequences, as well as coordinate Federal investments related to climate change education. In a broader sense, the implementation of the proposed Interagency Taskforce on Climate Change Communication and Education will serve the evolving USGCRP mandates around cross-cutting, thematic elements, as recommended by the National Research Council (NRC, 2009) and the U.S. Climate Change Science Program Revised Research Plan: An update to the 2003 Strategic Plan (USGCRP, 2008), to help the Federal government “capitalize on its investments and aid in the development of increased climate literacy for the Nation.” This session will update the participants on the work to date and the near term coordinated plans

    Studies have suggested that the default mode network is active during mind wandering, which is often experienced intermittently during sustained attention tasks. Conversely, an anticorrelated task-positive network is thought to subserve various forms of attentional processing. Understanding how these two systems work together is central for understanding many forms of optimal and sub-optimal task performance. Here we present a basic model of naturalistic cognitive fluctuations between mind wandering and attentional states derived from the practice of focused attention meditation. This model proposes four intervals in a cognitive cycle: mind wandering, awareness of mind wandering, shifting of attention, and sustained attention. People who train in this style of meditation cultivate their abilities to monitor cognitive processes related to attention and distraction, making them well suited to report on these mental events. Fourteen meditation practitioners performed breath-focused meditation while undergoing fMRI scanning. When participants realized their mind had wandered, they pressed a button and returned their focus to the breath. The four intervals above were then constructed around these button presses. We hypothesized that periods of mind wandering would be associated with default mode activity, whereas cognitive processes engaged during awareness of mind wandering, shifting of attention and sustained attention would engage attentional subnetworks. Analyses revealed activity in brain regions associated with the default mode during mind wandering, and in salience network regions during awareness of mind wandering. Elements of the executive network were active during shifting and sustained attention. Furthermore, activations during these cognitive phases were modulated by lifetime meditation experience. These findings support and extend theories about cognitive correlates of distributed brain networks.

  2. Focused attention vs. crossmodal signals paradigm: Deriving predictions from the time-window-of-integration model

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available In the crossmodal signals paradigm (CSP participants are instructed to respond to a set of stimuli from different modalities, presented more or less simultaneously, as soon as a stimulus from any modality has been detected. In the focused attention paradigm (FAP, on the other hand, responses should only be made to a stimulus from a pre-defined target modality and stimuli from non-target modalities should be ignored. Whichever paradigm is being applied, a typical result is that responses tend to be faster to crossmodal stimuli than to unimodal stimuli, a phenomenon often referred to as 'crossmodal interaction'. Here we investigate predictions of the time-window-of-integration (TWIN modeling framework previously proposed by the authors. It is shown that TWIN makes specific qualitative and quantitative predictions on how the two paradigms differ with respect to the probability of multisensory integration and the amount of response enhancement, including the effect of stimulus intensity ('inverse effectiveness'. Introducing a decision-theoretic framework for TWIN further allows comparing the two paradigms with respect to the predicted optimal time window size and its dependence on the prior probability that the crossmodal stimulus information refers to the same event. In order to test these predictions, experimental studies that systematically compare crossmodal effects under stimulus conditions that are identical except for the CSP-FAP instruction should be performed in the future.

  3. Maximizing Performance: Augmented Feedback, Focus of Attention, and/or Reward?

    Different approaches like providing augmented feedback (aF), applying an external focus of attention (EF), or rewarding participants with money (RE) have been shown to instantly enhance motor performance. So far, these approaches have been tested either in separate studies or directly against each other. However, there is no study that combined aF, EF, and/or RE to test whether this provokes additional benefits. The aim of the present study was therefore to identify the most powerful combination. Eighteen participants performed maximal countermovement jumps in six different conditions: neutral (NE), aF, RE, aF + EF, aF + RE, and aF + EF + RE. Participants demonstrated the highest jump heights with aF + EF, followed by aF + EF + RE, aF + RE, aF, RE, and finally, NE. Activity of the M. rectus femoris differed significantly between conditions resulting in lower muscular activity in aF + EF and aF + EF + RE compared with NE. All other parameters, such as ground reaction forces and joint angles, were comparable across conditions. This is the first study showing superior performance when combining aF with EF. As reduced muscular activity was found only in conditions with EF, it is argued in line with the constrained action hypothesis that adopting an EF improves movement efficiency. In contrast, aF seems to rather enhance (intrinsic) motivation. However, monetary reward did not further amplify performance.

  4. Can sensory attention focused exercise facilitate the utilization of proprioception for improved balance control in PD?

    2015-02-01

    Impaired sensory processing in Parkinson's disease (PD) has been argued to contribute to balance deficits. Exercises aimed at improving sensory feedback and body awareness have the potential to ameliorate balance deficits in PD. Recently, PD SAFEx™, a sensory and attention focused rehabilitation program, has been shown to improve motor deficits in PD, although balance control has never been evaluated. The objective of this study was to measure the effects of PD SAFEx™ on balance control in PD. Twenty-one participants with mild to moderate idiopathic PD completed 12 weeks of PD SAFEx™ training (three times/week) in a group setting. Prior to training, participants completed a pre-assessment evaluating balance in accordance with an objective, computerized test of balance (modified clinical test of sensory integration and balance (m-CTSIB) and postural stability testing (PST)) protocols. The m-CTSIB was our primary outcome measure, which allowed assessment of balance in both eyes open and closed conditions, thus enabling evaluation of specific sensory contributions to balance improvement. At post-test, a significant interaction between time of assessment and vision condition (p=.014) demonstrated that all participants significantly improved balance control, specifically when eyes were closed. Balance control did not change from pre to post with eyes open. These results provide evidence that PD SAFEx™ is effective at improving the ability to utilize proprioceptive information, resulting in improved balance control in the absence of vision. Enhancing the ability to utilize proprioception for individuals with PD is an important intermediary to improving balance deficits.

    Although learning through a computer interface has become increasingly common, little is known about how to best structure video-recorded lectures to optimize learning. In 2 experiments, we examine changes in focused attention and the ability for students to integrate knowledge learned during a 40-min video-recorded lecture. In Experiment 1, we demonstrate that interpolating a lecture with memory tests (tested group), compared to studying the lecture material for the same amount of time (restudy group), improves overall learning and boosts integration of related information learned both within individual lecture segments and across the entire lecture. Although mind wandering rates between the tested and restudy groups did not differ, mind wandering was more detrimental for final test performance in the restudy group than in the tested group. In Experiment 2, we replicate the findings of Experiment 1, and additionally show that interpolated tests influence the types of thoughts that participants report during the lecture. While the tested group reported more lecture-related thoughts, the restudy group reported more lecture-unrelated thoughts; furthermore, lecture-related thoughts were positively related to final test performance, whereas lecture-unrelated thoughts were negatively related to final test performance. Implications for the use of interpolated testing in video-recorded lectures are discussed. (PsycINFO Database Record

    Using Focus of Attention (FoA) as a perceptual process in image and video compression belongs to well-known approaches to increase coding efficiency. It has been shown that foveated coding, when compression quality varies across the image according to region of interest, is more efficient than the alternative coding, when all region are compressed in a similar way. However, widespread use of such foveated compression has been prevented due to two main conflicting causes, namely, the complexity and the efficiency of algorithms for FoA detection. One way around these is to use as much information as possible from the scene. Since most video sequences have an associated audio, and moreover, in many cases there is a correlation between the audio and the visual content, audiovisual FoA can improve efficiency of the detection algorithm while remaining of low complexity. This paper discusses a simple yet efficient audiovisual FoA algorithm based on correlation of dynamics between audio and video signal components. Results of audiovisual FoA detection algorithm are subsequently taken into account for foveated coding and compression. This approach is implemented into H.265/HEVC encoder producing a bitstream which is fully compliant to any H.265/HEVC decoder. The influence of audiovisual FoA in the perceived quality of high and ultra-high definition audiovisual sequences is explored and the amount of gain in compression efficiency is analyzed.

    The present investigation studied the effect of focus of attention and type of practice on self-efficacy and learning during a demonstration of the dart-throwing skill. 48 university students (M = 22.5 yr., SD = 3.6) without any experience of dart throwing were divided into four groups according to the type of practice (physical and observational) and focus of attention (internal and external) and practiced a dart-throwing task. Self-efficacy in dart throwing was measured at the pre-test, acquisition, and transfer phases. The internal-focus group concentrated on their limb function, whereas the external-focus group concentrated on the darts and the target during the demonstration. Observational groups only watched during the acquisition phase, then performed the task in the retention and transfer phases. There was a main effect of focus of attention in the retention and transfer phases after controlling self-efficacy, with external focus groups showing higher performance than internal focus groups. External focus of attention could facilitate the acquisition of a motor skill during observation and may build and/or be supported by self-efficacy.

    Full Text Available Objective: The aim of this study was to evaluate the impact of the external focus of attention on the rotator cuff muscle activity for the timely hit forehand drive by table tennis players. Methods: Twelve professional table tennis players with mean age of 26.5 years voluntarily participated in this study. The electrical activities of the muscles of the shoulder girdle using M.A 300 machine and bipolar electrodes surface under two conditions .First with external focus of attention and then without such attention were recorded, first without any guidance blows forehand drive was carried out by subjects (without focus. Then such subject was asked to focus their attention on the area marked for the ball landing (external focus of attention.      Muscle activities in both preparation and tapping phases were analyzed the three –dimensional (200 Hz, Vicon, with four camera series T motion analysis system was used to obtain the data. Data was analyzed by running reported measures ANOVA at a significance level of p0.05 but the different between the intensity of muscle activity was meaningful. This suggests that there is a mutual influence between the two attention factors and muscles (p=0.03, that is, orientation can have a significant effect on the severity of muscle contraction. Intensities of muscle contraction in the preparation and tapping were different (p<0.05. Conclusion: On the forehand drive technique, the anterior deltoid muscle has the most activity. The type of focus and attention had a significant impact on the change of activity of muscles relative to each other, and the greatest impact is on the reduction of activity of the infraspinatus muscle. This type of focus delays fatigue and results in an increase in the efficiency of neuromuscular in the activities of skills.

    The concept of attention has a prominent place in cognitive psychology. Attention can be directed not only to perceptual information, but also to information in working memory (WM). Evidence for an internal focus of attention has come from the retro-cue effect: Performance in tests of visual WM is improved when attention is guided to the test-relevant contents of WM ahead of testing them. The retro-cue paradigm has served as a test bed to empirically investigate the functions and limits of the focus of attention in WM. In this article, we review the growing body of (behavioral) studies on the retro-cue effect. We evaluate the degrees of experimental support for six hypotheses about what causes the retro-cue effect: (1) Attention protects representations from decay, (2) attention prioritizes the selected WM contents for comparison with a probe display, (3) attended representations are strengthened in WM, (4) not-attended representations are removed from WM, (5) a retro-cue to the retrieval target provides a head start for its retrieval before decision making, and (6) attention protects the selected representation from perceptual interference. The extant evidence provides support for the last four of these hypotheses.

    2011-04-01

    The aim of this study was to determine the effects of distraction and focused attention on both food intake and accuracy of perceived intake in women with non-clinical levels of disordered eating. In a laboratory study, twenty-seven young women consumed three identical pasta meals once a week for three consecutive weeks. Meals were eaten ad libitum during a control and two test conditions, in which attention was either diverted away from (distraction condition) or directed towards food-related stimuli (focused attention condition). They also completed the drive for thinness, bulimia and body dissatisfaction subscales of the Eating Disorders Inventory-2. Intake was significantly higher in the distraction than in the control or focused attention conditions, but was not related to eating psychopathology. A measure of accuracy of perceived intake indicated that drive for thinness was associated with overestimation of food intake in the focused attention condition. This study suggests that distraction could promote food intake in all non-clinical consumers, irrespective of individual differences in eating behaviours. Furthermore, it suggests that those with a high drive for thinness may overestimate intake when required to focus on their food. These findings could have implications for mealtime interventions in the treatment of eating disorders. Copyright © 2010 Elsevier Ltd. All rights reserved.

  13. Role of Working Memory Storage and Attention Focus Switching in Children’s Comprehension of Spoken Object Relative Sentences

    Directory of Open Access Journals (Sweden)

    Mianisha C. Finney

    2014-01-01

    Full Text Available The present study evaluated a two-mechanism memory model of the online auditory comprehension of object relative (OR sentences in 7–11-year-old typically developing children. Mechanisms of interest included working memory storage (WMS and attention focus switching. We predicted that both mechanisms would be important for comprehension. Forty-four children completed a listening span task indexing WMS, an auditory attention focus switching task, and an agent selection task indexing spoken sentence comprehension. Regression analyses indicated that WMS and attention focus switching accuracy each accounted for significant and unique variance in the children’s OR comprehension after accounting for age. Results were interpreted to suggest that WMS is important for OR comprehension by supporting children’s ability to retain both noun phrase 1 and noun phrase 2 prior to their reactivating noun phrase 1 from memory in order to integrate it into a developing structure. Attention focus switching was interpreted to be critical in supporting children’s noun phrase 1 reactivation, as they needed to switch their focus of attention momentarily away from ongoing language processing to memory retrieval.

    Full Text Available Ongoing debate surrounds the capacity and characteristics of the focus of attention. The present study investigates whether a pattern of larger recency effects and smaller primacy effects reported in previous working memory studies is specific to task conditions used in those studies, or generalizes across manipulations of task-demand. Two experiments varied task-demands by requiring participants to remember lists of letters and to then respond to a subsequent two-item probe by indicating either the item that was presented later in the list (judgment of recency or the item was presented earlier (judgment of primacy. Analyses tested the prediction that a WM task emphasizing later items in a list (judgment of recency would encourage exaggerated recency effects and attenuated primacy effects, while a task emphasizing earlier items (judgment of primacy would encourage exaggerated primacy effects and attenuated recency effects. Behavioral results from two experiments confirmed this prediction. In contrast to past studies, fMRI contrasts revealed no brain regions where activity was significantly altered by the presence of recency items in the probe, for either task condition. However, presence of the primacy item in the probe significantly influenced activity in frontal lobe brain regions linked to active maintenance, but the location and direction of activation changes varied as a function of task instructions. In sum, two experiments demonstrate that the behavioral and neural signatures of WM, specifically related to primacy and recency effects, are dependent on task-demands. Findings are discussed as they inform models of the structure and capacity of WM.

    2016-01-01

    Recent studies show that a single bout of meditation can impact information processing. We were interested to see whether this impact extends to attentional focusing and the top-down control over irrelevant information. Healthy adults underwent brief single bouts of either focused attention meditation (FAM), which is assumed to increase top-down control, or open monitoring meditation (OMM), which is assumed to weaken top-down control, before performing a global-local task. While the size of the global-precedence effect (reflecting attentional focusing) was unaffected by type of meditation, the congruency effect (indicating the failure to suppress task-irrelevant information) was considerably larger after OMM than after FAM. Our findings suggest that engaging in particular kinds of meditation creates particular cognitive-control states that bias the individual processing style toward either goal-persistence or cognitive flexibility.

    Self-regulatory trainings can be an effective complementary treatment for mental health disorders. We investigated the effects of a six-week-focused meditation training on emotion and attention regulation in undergraduates randomly allocated to a meditation, a relaxation, or a wait-list control group. Assessment comprised a discrimination task that investigates the relationship between attentional load and emotional processing and self-report measures. For emotion regulation, results showed greater reduction in emotional interference in the low attentional load condition in meditators, particularly compared to relaxation. Only meditators presented a significant association between amount of weekly practice and the reduction in emotion interference in the task and significantly reduced image ratings of negative valence and arousal, perceived anxiety and difficulty during the task, and state and trait-anxiety. For attention regulation, response bias during the task was analyzed through signal detection theory. After training, meditation and relaxation significantly reduced bias in the high attentional load condition. Importantly, there was a dose-response effect on general bias: the lowest in meditation, increasing linearly across relaxation and wait-list. Only meditators reduced omissions in a concentrated attention test. Focused meditation seems to be an effective training for emotion and attention regulation and an alternative for treatments in the mental health context. PMID:23935694

    Impairments in social attention play a major role in autism, but little is known about their role in development after preschool. In this study, a public speaking task was used to study social attention, its moderators, and its association with classroom learning in elementary and secondary students with higher functioning autism spectrum disorder (HFASD). Thirty-seven students with HFASD and 54 age- and intelligence quotient (IQ)-matched peers without symptoms of ASD were assessed in a virtual classroom public speaking paradigm. This paradigm assessed the ability to attend to nine avatar peers seated at a table, while simultaneously answering self-referenced questions. Students with HFASD looked less frequently to avatar peers in the classroom while talking. However, social attention was moderated in the HFASD sample such that students with lower IQ, and/or more symptoms of social anxiety, and/or more attention deficit/hyperactivity disorder inattentive symptoms, displayed more atypical social attention. Group differences were more pronounced when the classroom contained social avatars versus nonsocial targets. Moreover, measures of social attention rather than nonsocial attention were significantly associated with parent report and objective measures of learning in the classroom. The data in this study support the hypothesis of the Social Attention Model of ASD that social attention disturbance remains part of the school-aged phenotype of autism that is related to syndrome-specific problems in social learning. More research of this kind would likely contribute to advances in the understanding of the development of the spectrum of autism and educational intervention approaches for affected school-aged children.

    In 2014, the world was startled by a sudden outbreak of Ebola. Although Ebola infections and deaths occurred almost exclusively in Guinea, Sierra Leone, and Liberia, few potential Western cases, in particular, caused a great stir among the public in Western countries. This study builds on the construal level theory to examine the relationship between psychological distance to an epidemic and public attention and sentiment expressed on Twitter. Whereas previous research has shown the potential of social media to assess real-time public opinion and sentiment, generalizable insights that further the theory development lack. Epidemiological data (number of Ebola infections and fatalities) and media data (tweet volume and key events reported in the media) were collected for the 2014 Ebola outbreak, and Twitter content from the Netherlands was coded for (1) expressions of fear for self or fear for others and (2) psychological distance of the outbreak to the tweet source. Longitudinal relations were compared using vector error correction model (VECM) methodology. Analyses based on 4500 tweets revealed that increases in public attention to Ebola co-occurred with severe world events related to the epidemic, but not all severe events evoked fear. As hypothesized, Web-based public attention and expressions of fear responded mainly to the psychological distance of the epidemic. A chi-square test showed a significant positive relation between proximity and fear: χ(2)2=103.2 (PPublic attention and fear for self in the Netherlands showed peaks when Ebola became spatially closer by crossing the Mediterranean Sea and Atlantic Ocean. Fear for others was mostly predicted by the social distance to the affected parties. Spatial and social distance are important predictors of public attention to worldwide crisis such as epidemics. These factors need to be taken into account when communicating about human tragedies.

    Background Impairments in social attention play a major role in autism, but little is known about their role in development after preschool. In this study a public speaking task was used to study social attention, its moderators, and its association with classroom learning in elementary and secondary students with higher functioning Autism Spectrum Disorder (HFASD). Method Thirty-seven students with HFASD and 54 age and IQ-matched peers without symptoms of ASD were assessed in a virtual classroom public speaking paradigm. This paradigm assessed the ability to attend to 9 avatar peers seated at a table, while simultaneously answering self-referenced questions. Results Students with HFASD looked less frequently to avatar peers in the classroom while talking. However, social attention was moderated in the HFASD sample such that students with lower IQ, and/or more symptoms of social anxiety, and/or more ADHD Inattentive symptoms, displayed more atypical social attention. Group differences were more pronounced when the classroom contained social avatars versus non-social targets. Moreover, measures of social attention rather than non-social attention were significantly associated with parent report and objective measures of learning in the classroom. Conclusions The data in this study supports the hypothesis of the Social Attention Model of ASD that social attention disturbance remains part of the school-aged phenotype of autism that is related to syndrome specific problems in social learning.

    Full Text Available Previous studies have demonstrated that an external focus can enhance motor learning compared to an internal focus. The benefits of adopting an external focus are attributed to the use of less effortful automatic control processes, while an internal focus relies upon more effort-intensive consciously controlled processes. The aim of this study was to compare the effectiveness of a distal external focus with an internal focus in the acquisition of a simulated driving task and subsequent performance in a competitive condition designed to increase state anxiety. To provide further evidence for the automatic nature of externally controlled movements, the study included heart rate variability (HRV as an index of mental effort. Sixteen participants completed 8 blocks of 4 laps in either a distal external or internal focus condition, followed by 2 blocks of 4 laps in the competitive condition. During acquisition, the performance of both groups improved; however, the distal external focus group outperformed the internal focus group. The poorer performance of the internal focus group was accompanied by a larger reduction in HRV, indicating a greater investment of mental effort. In the competition condition, state anxiety increased, and for both groups, performance improved as a function of the increased anxiety. Increased heart rate and self-reported mental effort accompanied the performance improvement. The distal external focus group also outperformed the internal focus group across both neutral and competitive conditions and this more effective performance was again associated with lower levels of HRV. Overall, the results offer support for the suggestion that an external focus promotes a more automatic mode of functioning. In the competitive condition, both foci enhanced performance and while the improved performance may have been achieved at the expense of greater compensatory mental effort, this was not reflected in HRV scores.

    As social scientists have investigated the political and social factors influencing public opinion in science-related policy debates, there has been growing interest in the implications of this research for public communication and outreach. Given the level of political polarization in the United States, much of the focus has been on partisan differences in public opinion, the strategies employed by political leaders and advocates that promote those differences, and the counter-strategies for overcoming them. Yet this focus on partisan differences tends to overlook the processes by which core beliefs about science and society impact public opinion and how these schema are often activated by specific frames of reference embedded in media coverage and popular discourse. In this study, analyzing cross-sectional, nationally representative survey data collected between 2002 and 2010, we investigate the relative influence of political partisanship and science-related schema on Americans' support for embryonic stem cell research. In comparison to the influence of partisan identity, our findings suggest that generalized beliefs about science and society were more chronically accessible, less volatile in relation to media attention and focusing events, and an overall stronger influence on public opinion. Classifying respondents into four unique audience groups based on their beliefs about science and society, we additionally find that individuals within each of these groups split relatively evenly by partisanship but differ on other important dimensions. The implications for public engagement and future research on controversies related to biomedical science are discussed.

  17. Centripetal versus centrifugal bias in visual line bisection: focusing attention on two hypotheses.

    Science.gov (United States)

    McCourt, M E; Garlinghouse, M; Slater, J

    2000-01-01

    A variety of stimulus factors have been shown to influence the degree of leftward displacement of perceived line midpoint (i.e., pseudoneglect), which typifies the performance of normal subjects in line bisection tasks [M.E. McCourt & G. Jewell: Neuropsychologia 37, 843-855 (1999); G. Jewell & M.E. McCourt: Neuropsychologia 38, 93-110 (2000)]. One such factor is the position of lines within the visual field, where two conflicting patterns of bisection error have been reported. Some authors report a centrifugal pattern of error, where perceived line midpoint shifts away from the vertical midline, regardless of line position, i.e., relatively leftward for leftward displaced lines and vice versa. Others have reported a centripetal pattern of bisection error, where perceived line midpoint is always displaced centrally, toward the vertical midline, regardless of line position. There is no satisfactory explanation for these discrepant findings. An experiment using a tachistoscopic forced-choice line bisection protocol is described which discloses that neurologically normal right-handed subjects (N=82) typically display a centrifugal pattern of bisection error when lines are azimuthally displaced over a relatively small range, whereas a centripetal pattern is observed when lines are displaced over a wider range. Results from ancillary control experiments, in which eye position was measured during testing, confirm that systematic differences in gaze direction do not occur as a function of line position, and thus cannot account for the different patterns of bisection error. We conclude that stimulus context significantly modulates the strategy with which observers deploy spatial attention. When line position is constant, or varies over a narrow range, observers hold attention steady and widen its aperture to accommodate the relevant range of spatial location. Centrifugal bisection error is thus produced by the asymmetric cueing effect of laterally displaced lines, according

    Postural threat can induce conscious involvement in movement control. This internal focus has been implicated in compromising attentional processing efficiency during postural control, leading to behavioral adaptations that might increase the risk of falling in the elderly. It is suggested that electroencephalography (EEG) coherence, or 'communication', between T3 (verbal-analytical) and Fz (motor-planning) regions may provide an objective measure of internal focus in learned movement skills. However, it is currently unknown whether this experimental technique can be applied to the control of gait and posture; skills which develop early in life, without the use of declarative knowledge/explicit verbal cues to guide performance. We validate the utility of the EEG T3-Fz coherence analysis in a postural task. A total of 24 young adults produced small voluntary swaying movements in medial-lateral or anterior-posterior direction under conditions that directed their attentional focus either internally or externally. Although EEG coherence was sensitive to voluntary changes in attentional focus, the lack of observed between-group (High/Low-trait-reinvestment) difference in coherence may suggest that younger adults cannot be assumed to utilize explicit verbal cues to control voluntary postural sway unless explicitly instructed to do so. As a result, while these results indicate that EEG T3-Fz is a valid technique for assessing attentional focus in postural tasks, our data do not support the clinical application of this method of analysis in providing an objective indication of trait-reinvestment in tasks involving voluntary postural sway.

    Full Text Available Lamenting the lack of public awareness of international events and U.S. foreign policy is not a particularly novel exercise; yet, explaining the process by which issues enter and exit the public realm remains a challenging endeavor. Despite contributions from researchers working in international relations and mass communication, explaining public inattentiveness continues to vex scholars. However, in his article, "Up and Down with Ecology: The 'Issue-Attention Cycle,'" Anthony Downs provides a parsimonious and tractable model of public opinion that can be applied to foreign policy issues.1 While Downs concerns himself exclusively with domestic issues, particularly environmental issues, his model has thepotential to contribute to our understanding of the relationship between the public and policymakers over critical issues such as international terrorism. With minor modifications, the model has the potential to explain public support for failed foreign policies as well. Downs' model, when applied to international terrorism, explains why policymakers seek simple solutions, why the public supports such solutions, and why the media fail to provide meaningful coverage of intractable issues such as international terrorism. Before discussing Downs' model, the basic tenets and shortcomings of some of the more prevalent theories of the relationship between public opinion and foreign policy are discussed below.

    Objective. We outline the role of race, racial resentment, and attentiveness to news in structuring public opinion toward the prosecution of the Jena Six, the name given to six African-American high school students who beat a white student, five of whom were subsequently charged with attempted second-degree murder.Method. We rely on a telephone survey of 428 registered voters collected in the aftermath of the protests in Jena, Louisiana.Results. Public reactions were heavily filtered by race and associated with measures of racial resentment. African Americans followed news about the protests more closely, believed race was the most important consideration in the decision to prosecute, and believed the decision to prosecute was the wrong decision. Racially conservative white respondents were less likely to believe race was the most important consideration in the decision to prosecute and were more likely to believe that the decision to prosecute was the right decision. Consistent with theories of agenda setting and framing, attentiveness to the news influenced perceptions regarding the importance of race in the decision to prosecute but not whether the decision was the right decision.Conclusions. At least within the context of the Deep South, race and racial attitudes continue to be an important predictor of public reactions to racially charged events. Attentiveness to the news influenced the lens through which events were interpreted, but not perceptions of whether the outcome was the right decision.

    Full Text Available Rajasree Nair, Shannon B MossBaylor Family Medicine Residency at Garland, Garland, Texas, USAAbstract: Attention-deficit hyperactivity disorder (ADHD is one of the most common psychiatric disorders in young adults and causes significant psychosocial impairment and economic burden to society. Because of the paucity of long-term evidence and lack of national guidelines for diagnosis and management of adult ADHD, most of the data are based on experience derived from management of childhood ADHD. This article reviews the current evidence for the diagnosis and management of adult ADHD with special emphasis on the role of methylphenidate hydrochloride preparations in its treatment. Methylphenidate hydrochloride, a stimulant that acts through the dopaminergic and adrenergic pathways, has shown more than 75% efficacy in controlling the symptoms of adult ADHD. Although concern for diversion of the drug exists, recent data have shown benefits in preventing substance use disorders in patients with adult ADHD.Keywords: adult ADHD, treatment, stimulants, methylphenidate hydrochloride

  6. Understanding the Correlations between Social Attention and Topic Trends of Scientific Publications

    2016-03-01

    Full Text Available Purpose: We propose and apply a simplified nowcasting model to understand the correlations between social attention and topic trends of scientific publications. Design/methodology/approach: First, topics are generated from the obesity corpus by using the latent Dirichlet allocation (LDA algorithm and time series of keyword search trends in Google Trends are obtained. We then establish the structural time series model using data from January 2004 to December 2012, and evaluate the model using data from January 2013. We employ a state-space model to separate different non-regression components in an observational time series (i.e. the tendency and the seasonality and apply the “spike and slab prior” and stepwise regression to analyze the correlations between the regression component and the social media attention. The two parts are combined using Markov-chain Monte Carlo sampling techniques to obtain our results. Findings: The results of our study show that (1 the number of publications on child obesity increases at a lower rate than that of diabetes publications; (2 the number of publication on a given topic may exhibit a relationship with the season or time of year; and (3 there exists a correlation between the number of publications on a given topic and its social media attention, i.e. the search frequency related to that topic as identified by Google Trends. We found that our model is also able to predict the number of publications related to a given topic. Research limitations: First, we study a correlation rather than causality between topics' trends and social media. As a result, the relationships might not be robust, so we cannot predict the future in the long run. Second, we cannot identify the reasons or conditions that are driving obesity topics to present such tendencies and seasonal patterns, so we might need to do “field” study in the future. Third, we need to improve the efficiency of our model by finding more efficient

    This chapter analyses the challenges related to evaluations of large-scale public sector reforms. It is based on a meta-evaluation of the evaluation of the reform of the Norwegian Labour Market and Welfare Administration (the NAV-reform) in Norway, which entailed both a significant reorganization...... of the central, regional and local government and a social policy reform. Meta-evaluations assess the usefulness of one or more evaluations and should not be confused with meta-analyses. The purpose of this meta-evaluation was to identify general principles for organizing the evaluations of large-scale public...... sector reforms. Based on the analysis, eight crucial points of attention when evaluating large-scale public sector reforms are elaborated. We discuss their reasons and argue that other countries will face the same challenges and thus can learn from the experiences of Norway....

    Full Text Available Objectives: The objectives of the present study were to study the pattern of tobacco use among rural adolescents (15-19 years and to find out reasons for use and non use of tobacco products. Materials and Methods : In the present community-based research, triangulation of qualitative (free list, focus group discussions and quantitative methods (survey was undertaken. The study was carried out in surrounding 11 villages of the Kasturba Rural Health Training Centre, Anji during January 2008 where 385 adolescents were selected by simple random sampling and interviewed by house to house visits. After survey, six focus group discussions were undertaken with adolescent boys. Results: About 68.3% boys and 12.4% girls had consumed any tobacco products in last 30 days. Out of boys who had consumed tobacco, 79.2% consumed kharra, and 46.4% consumed gutka. Among boys, 51.2% consumed it due to peer pressure, 35.2% consumed tobacco as they felt better, and five percent consumed tobacco to ease abdominal complaints and dental problem. Among girls, 72% used dry snuff for teeth cleaning, 32% and 20% consumed tobacco in the form of gutka and tobacco & lime respectively. The reasons for non use of tobacco among girls were fear of cancer (59%, poor oral health (37.9%. Among non consuming boys it was fear of cancer (58.6%, poor oral health (44.8% and fear of getting addiction (29.3%. According to FGD respondents, few adolescent boys taste tobacco by 8-10 years of age, while girls do it by 12-13 years. Peer pressure acts as a pro tobacco influence among boys who are outgoing and spend more time with their friends. They prefer to consume freshly prepared kharra which was supposed to be less strong (tej than gutka. Tobacco is being used in treatment of some health problems. Tobacco is chewed after meals for better digestion, given to ease toothache, pain in abdomen and to induce vomiting in suicidal insecticide poisoning. Conclusion: The current consumption of any

    Full Text Available Social networking sites (SNSs provide users with an efficient interface for distributing information, such as photos or wall posts, to many others simultaneously. We demonstrated experimentally that this type of indiscriminate one-to-many (i.e., monologue communication may induce self-focused attention and thereby impair perspective taking. The present study used multiple paradigms to explore the link between engaging in online one-to-many communication and a decrease in perspective taking. Experiment 1 revealed that Facebookers who published a personal photo to the public or their friends were less likely to adopt another person's visual perspective than were those in the control group. Experiment 2 showed that Facebookers who engaged in indiscriminate one-to-many wall posting were more likely than those in the control group to rely heavily on their own perspectives. A state of self-focus, as measured by greater Stroop interference in naming the color of self-relevant versus neutral words, mediated the detrimental effect of indiscriminate one-to-many communication on cognitive perspective taking. These findings suggest that indiscriminate one-to-many communication on SNSs may promote public self-focus, leading to self-referential processing when making social judgments. Online monologue communication may be more harmful to perspective taking than previously understood.

    Full Text Available Frontal midline theta rhythm (Fmθ appears widely distributed over medial prefrontal areas in EEG recordings, indicating focused attention. Although mental calculation is often used as an attention-demanding task, little has been reported on calculation-related activation in Fmθ experiments. In this study we used spatially filtered MEG and permutation analysis to precisely localize cortical generators of the magnetic counterpart of Fmθ, as well as other sources of oscillatory activity associated with mental calculation processing (i.e., arithmetic subtraction. Our results confirmed and extended earlier EEG/MEG studies indicating that Fmθ during mental calculation is generated in the dorsal anterior cingulate and adjacent medial prefrontal cortex. Mental subtraction was also associated with gamma event-related synchronization, as an index of activation, in right parietal regions subserving basic numerical processing and number-based spatial attention. Gamma event-related desynchronization appeared in the right lateral prefrontal cortex, likely representing a mechanism to interrupt neural activity that can interfere with the ongoing cognitive task.

    Full Text Available According to several conceptualizations of meditation, the interplay between brain systems associated to self-related processing, attention and executive control is crucial for meditative states and related traits. We used magnetoencephalography to investigate such interplay in a highly selected group of virtuoso meditators (Theravada Buddhist monks, with long-term training in the two main meditation styles: focused attention (FA and open monitoring (OM meditation. Specifically, we investigated the differences between FA meditation, OM meditation and resting state in the coupling between the posterior cingulate cortex, core node of the Default Mode Network (DMN implicated in mind wandering and self-related processing, and the whole brain, with a recently developed phase coherence approach. Our findings showed a state dependent coupling of PCC to nodes of the DMN and of the executive control brain network in the alpha frequency band (8-12 Hz, related to different attentional and cognitive control processes in FA and OM meditation, consistently with the putative role of alpha band synchronization in the functional mechanisms for attention and consciousness. The coupling of posterior cingulate cortex with left medial prefrontal cortex and superior frontal gyrus characterized the contrast between the two meditation styles in a way that correlated with meditation expertise. These correlations may be related to a higher mindful observing ability and a reduced identification with ongoing mental activity in more expert meditators. Notably, different styles of meditation and different meditation expertise appeared to modulate the dynamic balance between fronto-parietal and DMN networks. Our results support the idea that the interplay between the DMN and the fronto-parietal network in the alpha band is crucial for the transition from resting state to different meditative states.

    According to several conceptualizations of meditation, the interplay between brain systems associated to self-related processing, attention and executive control is crucial for meditative states and related traits. We used magnetoencephalography (MEG) to investigate such interplay in a highly selected group of "virtuoso" meditators (Theravada Buddhist monks), with long-term training in the two main meditation styles: focused attention (FA) and open monitoring (OM) meditation. Specifically, we investigated the differences between FA meditation, OM meditation and resting state in the coupling between the posterior cingulate cortex, core node of the Default Mode Network (DMN) implicated in mind wandering and self-related processing, and the whole brain, with a recently developed phase coherence approach. Our findings showed a state dependent coupling of posterior cingulate cortex (PCC) to nodes of the DMN and of the executive control brain network in the alpha frequency band (8-12 Hz), related to different attentional and cognitive control processes in FA and OM meditation, consistently with the putative role of alpha band synchronization in the functional mechanisms for attention and consciousness. The coupling of PCC with left medial prefrontal cortex (lmPFC) and superior frontal gyrus characterized the contrast between the two meditation styles in a way that correlated with meditation expertise. These correlations may be related to a higher mindful observing ability and a reduced identification with ongoing mental activity in more expert meditators. Notably, different styles of meditation and different meditation expertise appeared to modulate the dynamic balance between fronto-parietal (FP) and DMN networks. Our results support the idea that the interplay between the DMN and the FP network in the alpha band is crucial for the transition from resting state to different meditative states.

    Public health program graduates need leadership skills to be effective in the complex, changing public health environment. We propose a new paradigm for schools of public health in which technical and leadership skills have equal priority as core competencies for graduate students. Leadership education should focus on the foundational skills necessary to effect change independent of formal authority, with activities offered at varying levels of intensity to engage different students. Leadership development initiatives should be practice based, process focused, interdisciplinary, diversity based, adaptive, experimental, innovative, and empowering, and they should encourage authenticity. Leadership training in graduate programs will help lay the groundwork for public health professionals to have an immediate impact in the workforce and to prioritize continuous leadership development throughout their careers.

Two experiments, on lever sequencing and basketball free throws, respectively, are reported that successfully tested these time-referenced predictions, i.e., showing that muscular activity is selectively increased and compensatory variability selectively decreased at movement-related nodal points if these points are in the focus of attention.

    Full Text Available Cognitive deficits are reported in diabetes mellitus type 2 (DM2. Previous research has shown that music-based intervention can not only reduce hyperglycemia but also target cognitive functions as well as stress. The aim of this exploratory study was to understand the effect of active participation in music therapy (MT on the cognitive deficits of DM2 patients. MT of twenty sessions was carried out with three participants with DM2. Serum cortisol, perceived stress, Color Trail Test (1 and 2, and verbal n-back (1 and 2 tests were used to measure the outcomes. Feedback was taken for the subjective ratings and satisfaction of the participants. Stress and cortisol reduced and focused attention and working memory improved in varying degrees. Subjectively, participants reported having benefitted from the intervention. This is the first attempt to investigate the effect of music-based intervention on cognitive function in DM2 patients using case study approach.

    2014-06-01

    Full Text Available It has been demonstrated within the literature that the practice of customer focus is significantly associated with customer satisfaction. However, the possibility that the construct of customer focus may affect other relevant measures remains underexplored. As such, this paper discusses the effect that customer focus has on organizational performance, operating upon the premise that customer satisfaction is an end result of other relevant performance measures such as employee satisfaction, innovation, and cost benefits. Data were collected from 205 managers within the public service sector, all of whom were directly involved with the process of customer focus. The results of this study revealed that customer focus is a significant predictor of employee satisfaction, innovation, and customer satisfaction. The structural model developed also indicated that there is an indirect relationship between customer focus and customer satisfaction, as determined by employee satisfaction. In addition, the effect of customer focus on innovation is mediated by employee satisfaction. Therefore, this model implies that the practice of customer focus may enable public firms to increase their levels of performance.

    Full Text Available Two examples that allow surmising the possibilities and obstacles of strategic alliances between the civil society and local governments seeking to develop programs that help solve the problems the community demands are featured in this research. The studies that were analyzed take place in the State of Baja California, and are based on documentary information and on interviews with key informants, which in this case, are the program leaders. The first of them has to do with the experience of a migrant support office in Mexicali, which is under the exclusive direction of a civil organization; while the second entails a program for the attention of migrants that were deported from the United States, whereby such program has been used by the federal government to spearhead a more encompassing public policy in the regional sphere. The two examples portray innovative public stewardship cases. The breakthroughs and obstacles to carry out such types of processes are presented. Furthermore, it is concluded that these two examples may be the seed of a new governance.

    Mindfulness meditation is a form of attention control training. The training exercises the ability to repeatedly focus attention. We addressed the activation changes related to an 8-weeks mindfulness-oriented focused attention meditation training on an initially naïve subject cohort. Before and after training participants underwent an fMRI experiment, thus, although not strictly a cross over design, they served as their internal own control. During fMRI they exercised focused attention on breathing and body scan as compared to resting. We found increased and decreased activation in different parts of the prefrontal cortex (PFC) by comparing pre- vs. post-mindfulness training (MT) during breathing and body scan meditation exercises that were compared against their own resting state. In the post-MT (vs. pre-MT) meditation increased activation in the right dorsolateral PFC and in the left caudate/anterior insula and decreased activation in the rostral PFC and right parietal area 3b. Thus a brief mindfulness training caused increased activation in areas involved in sustaining and monitoring the focus of attention (dorsolateral PFC), consistent with the aim of mindfulness that is exercising focused attention mechanisms, and in the left caudate/anterior insula involved in attention and corporeal awareness and decreased activation in areas part of the "default mode" network and is involved in mentalizing (rostral PFC), consistent with the ability trained by mindfulness of reducing spontaneous mind wandering.

    Full Text Available Aim: The purpose of the present study was to investigate the effect of variability of attentional focus distance by self-talk on the learning of table tennis backhand. Methods: Therefore, 80 high school girls by mean age 16(±0/62 yr. were randomly selected from sport school of Sanandaj and assigned to 5 groups. After pretest, the participants performed 180 forehand strokes during 6 sessions with repeating the words “slightly rotation” in the internal focus group “slightly open” in the near external focus group, “over the net” in the far external focus group, and each of the words “slightly rotation, slightly open, and over the net” respectively in each 2 sessions in the increasing distance of attentional focus group. Control group performed without self-talk during acquisition phase. Retention test was performed 48 hours after acquisition test in the same situation without self-talk, and after half an hour break, transfer test was done by changing the direction of target (parallel forehand without self-talk. The accuracy and the pattern of forehand strokes were measured by a 5 point-scale (Liao and Masters, 2001 and researcher-made scale, respectively. At the end of acquisition phase, participants filled out the frequency and self-talk beliefs questionnaire. Results: According to the results of 2-factor mixed ANOVA, acquisition, retention, and transfer of backhand accuracy in internal focus of attention group were significantly lower than other groups (p<0.05. Furthermore, the effect of increasing attentional focus distance on acquisition of backhand pattern was significant. The effect of near external attentional focus on retention of pattern was significant. But transfer of stroke pattern in control group was significantly more than far external focus group (p<0.05. Conclusions: Thus, it is recommended to use self-talk by increasing attentional focus and near external attentional focus and not to use internal focus of

    Full Text Available Abstract Background Food allergy prevalence is increasing in US children. Presently, the primary means of preventing potentially fatal reactions are avoidance of allergens, prompt recognition of food allergy reactions, and knowledge about food allergy reaction treatments. Focus groups were held as a preliminary step in the development of validated survey instruments to assess food allergy knowledge, attitudes, and beliefs of parents, physicians, and the general public. Methods Eight focus groups were conducted between January and July of 2006 in the Chicago area with parents of children with food allergy (3 groups, physicians (3 groups, and the general public (2 groups. A constant comparative method was used to identify the emerging themes which were then grouped into key domains of food allergy knowledge, attitudes, and beliefs. Results Parents of children with food allergy had solid fundamental knowledge but had concerns about primary care physicians' knowledge of food allergy, diagnostic approaches, and treatment practices. The considerable impact of children's food allergies on familial quality of life was articulated. Physicians had good basic knowledge of food allergy but differed in their approach to diagnosis and advice about starting solids and breastfeeding. The general public had wide variation in knowledge about food allergy with many misconceptions of key concepts related to prevalence, definition, and triggers of food allergy. Conclusion Appreciable food allergy knowledge gaps exist, especially among physicians and the general public. The quality of life for children with food allergy and their families is significantly affected.

    Estimating cognitive abilities in patients suffering from Disorders of Consciousness remains challenging. One cognitive task to address this issue is the so-called own name paradigm, in which subjects are presented with first names including the own name. In the active condition, a specific target name has to be silently counted. We recorded EEG during this task in 24 healthy controls, 8 patients suffering from Unresponsive Wakefulness Syndrome (UWS) and 7 minimally conscious (MCS) patients. EEG was analysed with respect to amplitude as well as phase modulations and connectivity. Results showed that general reactivity in the delta, theta and alpha frequency (event-related de-synchronisation, ERS/ERD, and phase locking between trials and electrodes) toward auditory stimulation was higher in controls than in patients. In controls, delta ERS and lower alpha ERD indexed the focus of attention in both conditions, late theta ERS only in the active condition. Additionally, phase locking between trials and delta phase connectivity was highest for own names in the passive and targets in the active condition. In patients, clear stimulus-specific differences could not be detected. However, MCS patients could reliably be differentiated from UWS patients based on their general event-related delta and theta increase independent of the type of stimulus. In conclusion, the EEG signature of the active own name paradigm revealed instruction-following in healthy participants. On the other hand, DOC patients did not show clear stimulus-specific processing. General reactivity toward any auditory input, however, allowed for a reliable differentiation between MCS and UWS patients.

    Both neuropsychological and functional neuroimaging studies have identified that the posterior parietal lobe (PPL) is critical for the attention function. However, the unique role of distinct parietal cortical subregions and their underlying white matter (WM) remains in question. In this study, we collected both magnetic resonance imaging and diffusion tensor imaging (DTI) data in normal participants, and evaluated their attention performance using attention network test (ANT), which could isolate three different attention components: alerting, orienting and executive control. Cortical thickness, surface area and DTI parameters were extracted from predefined PPL subregions and correlated with behavioural performance. Tract-based spatial statistics (TBSS) was used for the voxel-wise statistical analysis. Results indicated structure-behaviour relationships on multiple levels. First, a link between the cortical thickness and WM integrity of the right inferior parietal regions and orienting performance was observed. Specifically, probabilistic tractography demonstrated that the integrity of WM connectivity between the bilateral inferior parietal lobules mediated the orienting performance. Second, the scores of executive control were significantly associated with the WM diffusion metrics of the right supramarginal gyrus. Finally, TBSS analysis revealed that alerting performance was significant correlated with the fractional anisotropy of local WM connecting the right thalamus and supplementary motor area. We conclude that distinct areas and features within PPL are associated with different components of attention. These findings could yield a more complete understanding of the nature of the PPL contribution to visuospatial attention.

    The development of early intervention strategies for children with symptoms of Attention Deficit Hyperactivity Disorder (ADHD) is important because it provides an opportunity to prevent severe problems in the future. The main purpose of this investigation was to determine the efficacy of a group training for the control of attention, working memory and impulsive behaviors, involving 5-year-old children with ADHD symptoms. Twenty-six children with ADHD symptoms and 26 with typical development were randomly divided in two conditions. Thirteen children in each group were assigned to the training condition and the other to the business as usual condition (normal class activity). Children who participated in the intervention showed an improvement in the tasks measuring their control of attention, impulsive behavior, and working memory. Moreover, children with typical development who attended the training also improved their competencies. The results confirm the importance of an early intervention for preschool-age children with ADHD symptoms. PMID:26300836

    2016-01-01

    Abdollahipour, Wulf, Psotta, and Nieto (2015) recently published data in the Journal of Sports Sciences to show that an external focus of attention promotes superior performance effects (gymnastics jump height and judged movement form score) when compared to internal or control foci during skill execution without an implement involved. While we do not contest the veracity of findings reported, nor others that have been used to support beneficial effects of an external focus of attention, in this Letter to the Editor we comment on considerable methodological limitations associated with this and previous studies that, we suggest, have resulted in serious theoretical oversights regarding the control of movement and, most crucially from our practitioner perspective, suboptimal recommendations for applied coaching practice. Specifically, we discuss the lack of consideration towards translational research in this area, the problematic nature of attentional focus cues employed, interpretation of findings in relation to other applied recommendations and coherence with mechanistic underpinning and, finally, the representative nature of task involved. In summary, while (laboratory) research evidence may appear to be conclusive, we suggest that the focus of attention effects are in need of more ecologically valid and rigorous testing as well as consideration of current coaching practices if it is to optimally serve the applied sporting domain that it purportedly aims to.

    For this article, we conducted a qualitative investigation of participants' reactions to five televised public service announcements (PSAs) that were aired as part of a large safer-sex mass media campaign to increase condom use among young adults. We conducted qualitative interviews (N = 139) to determine which features of PSAs participants thought were most effective in terms of attention and recall, perceived realism of characters and situations, and cognitive responses. Our analysis of the results highlights the importance of high-sensation-value messages for gaining attention as well as the critical role of personal relevance for enhancing perceptions of realism. Cognitive responses to PSAs were mostly positive, but there was evidence of third-person effects. That is, many participants indicated that the safer-sex messages were important for other people but not for themselves. We discuss the implications of our results for designing PSAs that are attention-catching, realistic, and persuasive.

    Background: Evidence supports the use of pricing interventions in achieving healthier behaviour at population level. The public acceptability of this strategy continues to be debated throughout Europe, Australasia and USA. We examined public attitudes towards, and beliefs about the acceptability of pricing policies to change health-related behaviours in the UK. The study explores what underlies ideas of acceptability, and in particular those values and beliefs that potentially compete with the evidence presented by policy-makers. Methods: Twelve focus group discussions were held in the London area using a common protocol with visual and textual stimuli. Over 300 000 words of verbatim transcript were inductively coded and analyzed, and themes extracted using a constant comparative method. Results: Attitudes towards pricing policies to change three behaviours (smoking, and excessive consumption of alcohol and food) to improve health outcomes, were unfavourable and acceptability was low. Three sets of beliefs appeared to underpin these attitudes: (i) pricing makes no difference to behaviour; (ii) government raises prices to generate income, not to achieve healthier behaviour and (iii) government is not trustworthy. These beliefs were evident in discussions of all types of health-related behaviour. Conclusions: The low acceptability of pricing interventions to achieve healthier behaviours in populations was linked among these responders to a set of beliefs indicating low trust in government. Acceptability might be increased if evidence regarding effectiveness came from trusted sources seen as independent of government and was supported by public involvement and hypothecated taxation.

    Attention-deficit/hyperactivity disorder is one of the most common behavioural disorders diagnosed in children. Children who have this disorder have difficulties regarding regulation of their emotions, maintaining attention and impulse control. Parents may need guidance in creating structure and predictable boundaries. One of the personnel who meet these families is the public health nurse. The aim of this study was to explore the public health nurses role in relation to these families. A qualitative explorative design with a phenomenographic approach was used. Interviews were performed with 19 nurses, six in group and one individual. In the data analyses, three descriptive categories emerged: 'supporting the family-unit', which describes the nurses supervising the parents and the child in everyday challenges; 'understanding the child', which describes how the public health nurses use professional competence and choose the time and arena to observe the child and; 'collaborating multidisciplinary', which describes how the public health nurses define their own role and conceive their collaboration with other professionals. The public health nurse (PHN)'s support for the parents and the entire family is important, and the PHN is the first encounter and trustful follower throughout the course of diagnosis and care. © 2013 Nordic College of Caring Science.

  6. La langue des journalistes est-elle dictée par le public ? Attentes supposées du public en Belgique francophone

    Full Text Available Le public a tendance à être sévère à l’égard du français des journalistes, qui constitue à la fois le reflet et le modèle de la langue de la société. Vérifier la validité de ces critiques par une approche scientifique pose des problèmes méthodologiques importants. En s’inscrivant dans une autre voie, cet article s’attache au discours métalinguistique des journalistes. Il vise à comprendre la manière dont les journalistes considèrent le français qu’ils utilisent dans leur pratique professionnelle, au travers de la « relation » qui les lie à leur public. Nous avons interrogé 15 journalistes belges francophones. Il ressort de nos entretiens que les médias dans lesquels travaillent ces journalistes ne développent pas de politiques linguistiques fortes. Néanmoins, le français des médias est largement autorégulé par une série de facteurs. Parmi ceux-ci figure le public, ou plutôt les attentes de ce public, telles qu’elles sont imaginées par les journalistes. En effet, les journalistes justifient souvent leurs attitudes linguistiques par des considérations directement liées à leur public. D’abord, la volonté d’être crédible auprès de leur public incite les journalistes à une correction de leur langage. Cette correction constituerait également une forme de respect envers le public. Ensuite, les journalistes sont sans cesse préoccupés par l’intelligibilité de leurs productions : ils veulent être compris par un public le plus large possible, ce qui conditionne leur usage de la langue. Par ailleurs, ils semblent investis d’une volonté d’être pédagogues en matière de langue, et mettent en avant leur devoir d’utiliser un français exemplaire. Enfin, les journalistes ne veulent manifestement pas parler comme leur public, mais conformément à ce que ce public attend d’eux. Au final, faire parler les journalistes de la langue revient inévitablement à les faire parler de leur public

    The presence of attention-deficit/hyperactive disorder (ADHD) symptoms and impaired attention performance are commonly noted in individuals with autism spectrum disorder (ASD). However, little is known about attention performance in their unaffected siblings. This study aimed to investigate the ADHD-related traits and attention performance in unaffected siblings of probands with autism and Asperger syndrome (AS), as well as the clinical correlates of ADHD-related traits. We assessed the intention, hyperactivity-impulsivity, and oppositional symptoms, and attention profiles of 199 probands with a diagnosis of ASD (122 autism, 77 AS), their unaffected siblings, and 196 typically developing controls (TD) by their parents' reports on the ADHD-related symptoms and the Connors' Continuous Performance Test (CCPT), respectively. Compared to TD, unaffected siblings of ASD probands were more hyperactive/impulsive and oppositional, particularly unaffected siblings of AS probands. In CCPT, unaffected siblings of AS have intermediate levels of performance between probands with AS and TD on focused attention and sustained attention but were not statistically different from AS probands or TD in these attention profiles. In contrast, unaffected siblings of autism probands have significantly better CCPT performance when compared to autism probands but not to TD. In addition, stereotyped behaviors predicted ADHD-related traits in both sibling groups, but distinctive patterns of other correlates for ADHD-related traits were found between the two sibling groups. This work suggested that unaffected siblings of AS, but not autism, have more hyperactive/impulsive traits and a trend of pervasive attention deficits assessed by CCPT which might serve as potential endophenotypes for genetic studies in AS.

    To compare the long-term effects of external focus (EF) and internal focus (IF) of attention after 4 weeks of arm training. Randomized, repeated-measures, mixed analysis of variance. Outpatient clinic. Individuals with stroke and moderate-to-severe arm impairment living in the community (N=33; withdrawals: n=3). Four-week arm training protocol on a robotic device (12 sessions). Joint independence, Fugl-Meyer Assessment, and Wolf Motor Function Test measured at baseline, discharge, and 4-week follow-up. There were no between-group effects for attentional focus. Participants in both groups improved significantly on all outcome measures from baseline to discharge and maintained those changes at 4-week follow-up regardless of group assignment (joint independence EF condition: F1.6,45.4=17.74; P<.0005; partial η(2)=.39; joint independence IF condition: F2,56=18.66; P<.0005; partial η(2)=.40; Fugl-Meyer Assessment: F2,56=27.83; P<.0005; partial η(2)=.50; Wolf Motor Function Test: F2,56=14.05; P<.0005; partial η(2)=.35). There were no differences in retention of motor skills between EF and IF participants 4 weeks after arm training, suggesting that individuals with moderate-to-severe arm impairment may not experience the advantages of an EF found in healthy individuals. Attentional focus is most likely not an active ingredient for retention of trained motor skills for individuals with moderate-to-severe arm impairment, whereas dosage and intensity of practice appear to be pivotal. Future studies should investigate the long-term effects of attentional focus for individuals with mild arm impairment. Copyright © 2017 American Congress of Rehabilitation Medicine.

    The outbreak of the Ebola epidemic in West Africa in 2014 exerted enormous global public reaction via the Internet and social media. This study aimed to investigate and evaluate the public reaction to Ebola in China and identify the primitive correlation between possible influence factors caused by the outbreak of Ebola in West Africa and Chinese public attention via Internet surveillance. Baidu Index (BDI) and Sina Micro Index (SMI) were collected from their official websites, and the disease-related data were recorded from the websites of the World Health Organization (WHO), U.S. Centers for Disease Control and Prevention (CDC), and U.S. National Ministries of Health. The average BDI of Internet users in different regions were calculated to identify the public reaction to the Ebola outbreak. Spearman's rank correlation was used to check the relationship of epidemic trends with BDI and SMI. Additionally, spatio-temporal analysis and autocorrelation analysis were performed to detect the clustered areas with the high attention to the topic of "Ebola". The related news reports were collected from authoritative websites to identify potential patterns. The BDI and the SMI for "Ebola" showed a similar fluctuating trend with a correlation coefficient = 0.9 (p < 0.05). The average BDI in Beijing, Tibet, and Shanghai was higher than other cities. However, the disease-related indicators did not identify potential correlation with both indices above. A hotspot area was detected in Tibet by local autocorrelation analysis. The most likely cluster identified by spatiotemporal cluster analysis was in the northeast regions of China with the relative risk (RR) of 2.26 (p ≤ 0.01) from 30 July to 14 August in 2014. Qualitative analysis indicated that negative news could lead to a continuous increase of the public's attention until the appearance of a positive news report. Confronted with the risk of cross-border transmission of the infectious disease, online surveillance might be

    Neurofeedback is a nonpharmacological treatment for attention-deficit hyperactivity disorder (ADHD). We propose that operant conditioning of electroencephalogram (EEG) in neurofeedback training aimed to mitigate inattention and low arousal in ADHD, will be accompanied by changes in EEG bands' relative power. Patients were 18 children diagnosed with ADHD. The neurofeedback protocol ("Focus/Alertness" by Peak Achievement Trainer) has a focused attention and alertness training mode. The neurofeedback protocol provides one for Focus and one for Alertness. This does not allow for collecting information regarding changes in specific EEG bands (delta, theta, alpha, low and high beta, and gamma) power within the 2 to 45 Hz range. Quantitative EEG analysis was completed on each of twelve 25-minute-long sessions using a custom-made MatLab application to determine the relative power of each of the aforementioned EEG bands throughout each session, and from the first session to the last session. Additional statistical analysis determined significant changes in relative power within sessions (from minute 1 to minute 25) and between sessions (from session 1 to session 12). Analysis was of relative power of theta, alpha, low and high beta, theta/alpha, theta/beta, and theta/low beta and theta/high beta ratios. Additional secondary measures of patients' post-neurofeedback outcomes were assessed, using an audiovisual selective attention test (IVA + Plus) and behavioral evaluation scores from the Aberrant Behavior Checklist. Analysis of data computed in the MatLab application, determined that theta/low beta and theta/alpha ratios decreased significantly from session 1 to session 12, and from minute 1 to minute 25 within sessions. The findings regarding EEG changes resulting from brain wave self-regulation training, along with behavioral evaluations, will help elucidate neural mechanisms of neurofeedback aimed to improve focused attention and alertness in ADHD.

    Focusing attention is a way for animals to search for and to obtain food efficiently. This study examines whether a sit-and-wait forager, the orb-web spider Cyclosa octotuberculata, focuses its attention on limited foraging areas. Video records of foraging activity revealed that the spiders detected prey trapped in the west and east sectors of their web less frequently than prey trapped in the north and south sectors. Comparison of photos of the web hub area with and without spiders present revealed that the spiders pulled radii towards the centre when waiting for prey. Radius pulling is stronger in the north and south web sectors than in the west and east sectors, possibly causing more tension in radii running vertically. Experimental manipulation indicated that the spiders responded to prey quicker when thread tension was increased. The results suggest that C. octotuberculata focus their attention on the web areas above and below the spider by adjusting the tension in web threads; and this causes higher prey detection rates in these areas.

    This paper explores the role that technology can play in engaging pre-service teachers with the iterative, "messy" nature of model-based inquiry. Over the course of 5 weeks, 11 pre-service teachers worked in groups to construct models of diffusion using a computational animation and simulation toolkit, and designed lesson plans for the toolkit. Content analyses of group discussions and lesson plans document attention to content, representation, revision, and evaluation as interwoven aspects of modeling over the course of the workshop. When animating, only content and representation were heavily represented in group discussions. When simulating, all four aspects were represented to different extents across groups. Those differences corresponded with different planned uses for the technology during lessons: to teach modeling, to engage learners with one another's ideas, or to reveal student ideas. We identify specific ways in which technology served an important role in eliciting teachers' knowledge and goals related to scientific modeling in the classroom.

    The Framework Convention on Tobacco Control (FCTC) stresses the importance of scientific research. We examined the differences between 31 European countries regarding quantity and focus of tobacco control research publications. PubMed, Web of Science, Scopus, and PsycInfo were searched for peer-reviewed articles on tobacco, written by European authors, published between 2000 and 2012. For 2000, 2004, 2008, and 2012 we further identified the main focus of the publication. The volume of European tobacco control scientific publications had almost doubled. Scandinavian countries had most publications per inhabitant, while Bulgaria, Cyprus, Estonia, Latvia, Lithuania, Malta, Romania, Slovakia, and Slovenia had relatively little research output. There was a smaller increase in publications about harm from tobacco, relative to publications about treatment, and education, and to publications about environmental interventions. In 2012, 49% of all publications were about health, while the total number of publications on environmental interventions was relatively small (10%). Research output had almost doubled, in line with global trends, but is still unevenly distributed across Europe. Although we observed a shift in European publications away from the harm of tobacco towards protecting smokers and changing the environment, the field is still dominated by publications on smoking and health. © 2015 S.

    Full Text Available The current article was developed from several conclusions obtained during a new and interesting professional practice experience of psychology, consisting of the introduction of neuropsychological diagnosis and rehabilitation services in the public tertiary health system context. During its accomplishment, it was possible to get to know thoroughly about the sufferings that brain stoke damaged patients have to face day by day, demonstrating their imperious need to obtain some type of therapeutic support parallel to the physiatric treatment among the predefined procedures in the current level of coverage of the AUGE – GES program. From this reflection it is expected to open new ideas and contributions that help to expand nervous system diseases rehabilitation treatments for patients attended in the public system, nowadays limited to movement or of daily activities therapies. This need of updating the treatments, derivative of the newest conceptions of an integral human being (biological, social and psychic, demonstrate the importance of including neuropsychological diagnosis and rehabilitation as service of public health and its consideration as critical issue for the current and future health authorities.

    2012-03-01

    Built environment characteristics have been linked to health outcomes and health disparities. However, the effects of an environment on behavior may depend on human perception, interpretation, motivation, and other forms of human agency. We draw on epidemiological and ethical concepts to articulate a critique of research on the built environment and physical activity. We identify problematic assumptions and enumerate both scientific and ethical reasons to incorporate subjective perspectives and public engagement strategies into built environment research and interventions. We maintain that taking agency seriously is essential to the pursuit of health equity and the broader demands of social justice in public health, an important consideration as studies of the built environment and physical activity increasingly focus on socially disadvantaged communities. Attention to how people understand their environment and navigate competing demands can improve the scientific value of ongoing efforts to promote active living and health, while also better fulfilling our ethical obligations to the individuals and communities whose health we strive to protect.

    Learning disabilities and attention deficit disorders are chronic conditions that represent the most common diagnoses of students served in special education programs in the schools. In this article, we discuss specific problem areas that require decision advocacy on the part of the affected individual as well as his or her family. We briefly describe the requirements for teachers who specialize in this area of education as well as the nature of the conditions. We argue that education programs for individuals with such conditions must be tailored to offset the specific manifestations of the disability and its interactions with the requirements of the educational system. We also note that educational requirements are often dramatically different as students move from early education through the system toward high school graduation and, for many, into post-secondary education. We describe general procedures for advocacy that can be used to enhance educational programs across the spectrum of school placements. A section that specifically addresses advocacy for parents of students with these types of disabilities acknowledges the critical role that having a supportive parent plays in the development of successful education programs. We then address the specific issues that are likely to characterize educational problems at different levels of schooling. Among these are increased requirements for self-management and self-discipline as students move through the grades and increased emphasis on academic learning as students move into middle and secondary schools. The article also discusses instructional methods that are supported for students with such conditions as well as a brief description of several types of treatment that are considered to be ineffective for such students. Brief guidelines for recognizing both supported and contra-indicated educational programs are also provided. We conclude with resources for gathering information and making decisions that promote

Private organizations will not survive if they fail to acquire necessary resources through market competition. Public organizations, however, continue to survive because the government has provided financial support in order to enhance public interest. Only a few public organizations in Korea have closed. With the introduction of new public management since the economic crisis in 1997, however, public organizations have had to compete with private organizations. Public hospitals are not free to open or close their business. They are also controlled by the government in terms of their prices, management, budgets, and operations. As they pursue public interest by fulfilling the government’s order such as providing free or lower-priced care to the vulnerable population, they tend to provide a lower quality of care and suffer a financial burden. Employing a case study analysis, this study attempts to understand the external environment that local public hospitals face. The fundamental problem of local public hospitals in Korea is the value conflict between public interest and profitability. Local public hospitals are required to pursue public interest by assignment of a public mission including building a medical safety net for low-income patients and managing nonprofitable medical facilities and emergent health care situations. At the same time, they are required to pursue profitability by achieving high-quality care through competition and the operation of an independent, self-supporting system according to

The purpose of this research was to investigate how mass media use influences perceptions of threat from cancer and eastern equine encephalitis (EEE). Investigators performed a media content analysis of 253 health-related articles from 11 Massachusetts newspapers, then used logistic regression to analyze responses to a health communication survey of 613 Massachusetts adults. A greater proportion of cancer articles compared to those about EEE mentioned progress in combating the disease (61.0% vs. 16.2%, P media was related to higher odds of perceiving EEE as a threat (OR 2.14; 95% CI 1.03-4.45), and of perceiving EEE as a threat compared to cancer (OR 2.18; 95% CI 1.24-3.84). Media treatment of health stories that emphasize the novelty and unpredictability of EEE compared to cancer may lead to distorted perceptions of threat among news consumers.

    The rising global tide of antimicrobial resistance is a well-described phenomenon. Employing effective and innovative antimicrobial stewardship strategies is an essential approach to combat this public health threat. Education of the public and patients is paramount to enable the success of such strategies. A panel of hospital multidisciplinary healthcare professionals was set up and a short quiz containing true/false statements around antimicrobial stewardship and resistance was designed and piloted. An educational leaflet with the correct replies and supporting information was also produced and disseminated. Participants were recruited on a single day (18 November 2015) from the hospital outpatient clinics and the hospital outpatient pharmacy waiting room. One hundred and forty-five completed quizzes were returned, providing a total of 1450 answers. Overall, 934 of 1450 (64%) statements were scored correctly whilst 481 (33%) were scored incorrectly; 35 (3%) statements were left unscored. We speculate that these results may demonstrate that respondents understood the statements, as only a small proportion of statements were left unanswered. The question dealing with the definition of antimicrobial resistance and the question dealing with the definition of antimicrobial stewardship obtained the most incorrect replies (85% and 72%, respectively). However, a specific factual recall question regarding only one microorganism (MRSA) received the most correct responses (99%). We describe a simple, innovative method of engagement with patients and the general public to help educate and disseminate important public health messages around antimicrobial resistance and stewardship. We also identified the need for public health campaigns to address the knowledge gaps found around this topic. © The Author 2016.

    To investigate the biomedical scientist's perception of the prevailing publication culture. Qualitative focus group interview study. Four university medical centres in the Netherlands. Three randomly selected groups of biomedical scientists (PhD, postdoctoral staff members and full professors). Main themes for discussion were selected by participants. Frequently perceived detrimental effects of contemporary publication culture were the strong focus on citation measures (like the Journal Impact Factor and the H-index), gift and ghost authorships and the order of authors, the peer review process, competition, the funding system and publication bias. These themes were generally associated with detrimental and undesirable effects on publication practices and on the validity of reported results. Furthermore, senior scientists tended to display a more cynical perception of the publication culture than their junior colleagues. However, even among the PhD students and the postdoctoral fellows, the sentiment was quite negative. Positive perceptions of specific features of contemporary scientific and publication culture were rare. Our findings suggest that the current publication culture leads to negative sentiments, counterproductive stress levels and, most importantly, to questionable research practices among junior and senior biomedical scientists.

    Anticipatory processing, maladaptive attentional focus, and postevent processing are key cognitive constructs implicated in the maintenance of social anxiety disorder (SAD). The current study examined how treatment for SAD concurrently affects these three cognitive maintaining processes and how these processes are associated with each other as well as with symptom change from pre- to posttreatment. The sample consisted of 116 participants with SAD receiving group cognitive behavioral therapy. All three cognitive maintaining processes were measured relative to a speech task and again relative to a conversation task. Across both tasks, the three cognitive process variables demonstrated decreases from pre- to posttreatment. Within the same task, a slower rate of decrease in a specific cognitive process variable from pre- to posttreatment was predicted from higher pretreatment levels of either one or both of the other cognitive process variables. Additionally, higher levels of pretreatment conversation-related anticipatory processing and maladaptive attentional focus predicted a slower rate of decrease in social anxiety symptoms from pre- to posttreatment. Results are consistent with cognitive models of SAD and have important implications for enhancing existing treatments. Copyright © 2017. Published by Elsevier Ltd.

  10. How to Make the Ghosts in my Bedroom Disappear? Focused-Attention Meditation Combined with Muscle Relaxation (MR Therapy)—A Direct Treatment Intervention for Sleep Paralysis

    Sleep paralysis (SP) is a common state of involuntary immobility occurring at sleep onset or offset. It can include terrifying hypnogogic or hypnopompic hallucinations of menacing bedroom intruders. Unsurprisingly, the experience is associated with great fear and horror worldwide. To date, there exist no direct treatment intervention for SP. In this article, I propose for the first time a type of focused inward-attention meditation combined with muscle relaxation as a direct intervention to be applied during the attack, to ameliorate and possibly eliminate it (what could be called, meditation-relaxation or MR therapy for SP). The intervention includes four steps: (1) reappraisal of the meaning of the attack; (2) psychological and emotional distancing; (3) inward focused-attention meditation; (4) muscle relaxation. The intervention promotes attentional shift away from unpleasant external and internal stimuli (i.e., terrifying hallucinations and bodily paralysis sensations) unto an emotionally pleasant internal object (e.g., a positive memory). It may facilitate a relaxed meditative state characterized by a shift from sympathetic to parasympathetic dominance, associated with greater levels of alpha activity (which may lead to drowsiness and potentially sleep). The procedure may also reduce the initial panic and arousal that occur when realizing one is paralyzed. In addition, I present a novel Panic-Hallucination (PH) Model of Sleep Paralysis; describing how through escalating cycles of fear and panic-like autonomic arousal, a positive feedback loop is created that worsens the attack (e.g., leading to longer and more fearful episodes), drives content of hallucinations, and causes future episodes of SP. Case examples are presented to illustrate the feasibility of MR therapy for SP. PMID:26858675

    2011-06-01

    Public health attention to childhood obesity has increased in tandem with the growing epidemic, but despite this intense focus, successes in prevention have lagged far behind. There is a blind spot in our drive for childhood obesity prevention that prevents us from generating sufficiently broad solutions. Eating disorders and the constellation of perilous weight-control behaviors are in that blind spot. Evidence is mounting that obesity and eating disorders are linked in myriad ways, but entrenched myths about eating disorders undermine our ability to see the full range of leverage points to target in obesity preventive intervention studies. Our efforts to prevent childhood obesity can no longer afford to ignore eating disorders and the assemblage of related behaviors that persist unabated.

  18. Computing an optimal time window of audiovisual integration in focused attention tasks: illustrated by studies on effect of age and prior knowledge.

    Science.gov (United States)

    Colonius, Hans; Diederich, Adele

    2011-07-01

    The concept of a "time window of integration" holds that information from different sensory modalities must not be perceived too far apart in time in order to be integrated into a multisensory perceptual event. Empirical estimates of window width differ widely, however, ranging from 40 to 600 ms depending on context and experimental paradigm. Searching for theoretical derivation of window width, Colonius and Diederich (Front Integr Neurosci 2010) developed a decision-theoretic framework using a decision rule that is based on the prior probability of a common source, the likelihood of temporal disparities between the unimodal signals, and the payoff for making right or wrong decisions. Here, this framework is extended to the focused attention task where subjects are asked to respond to signals from a target modality only. Evoking the framework of the time-window-of-integration (TWIN) model, an explicit expression for optimal window width is obtained. The approach is probed on two published focused attention studies. The first is a saccadic reaction time study assessing the efficiency with which multisensory integration varies as a function of aging. Although the window widths for young and older adults differ by nearly 200 ms, presumably due to their different peripheral processing speeds, neither of them deviates significantly from the optimal values. In the second study, head saccadic reactions times to a perfectly aligned audiovisual stimulus pair had been shown to depend on the prior probability of spatial alignment. Intriguingly, they reflected the magnitude of the time-window widths predicted by our decision-theoretic framework, i.e., a larger time window is associated with a higher prior probability.

    2013-11-01

    In a previous analysis of the country of origin of papers published in Naunyn-Schmiedeberg's Archives of Pharmacology, a major shift toward contributions from emerging market countries, was noticed in comparison of 2010 to 2001 publications. Repeating such analysis for 2012 publications in the journal confirmed this trend. An interesting new trend was the emerging presence of papers from a variety of Islamic countries including Egypt. Based on this trend, we shortly review the history and current structure of pharmacology in Egypt. It appears that the presence of Egyptian pharmacology in international journals including pharmacology journals has sharply been increasing over the last two decades. Challenges for a continuation of this encouraging trend are being discussed.

  4. Me, myself, and I: Self-referent word use as an indicator of self-focused attention in relation to depression and anxiety

    Timo eBrockmeyer

    2015-10-01

    Full Text Available Self-focused attention (SFA is considered a cognitive bias that is closely related to depression. However, it is not yet well understood whether it represents a disorder-specific or a trans-diagnostic phenomenon and which role the valence of a given context is playing in this regard. Computerized quantitative text-analysis offers an integrative psycho-linguistic approach that may help to provide new insights into these complex relationships. The relative frequency of first-person singular pronouns in natural language is regarded as an objective, linguistic marker of SFA. Here we present two studies that examined the associations between SFA and symptoms of depression and anxiety in two different contexts (positive vs. negative valence, as well as the convergence between pronoun-use and self-reported aspects of SFA. In the first study, we found that the use of first-person singular pronouns during negative but not during positive memory recall was positively related to symptoms of depression and anxiety in patients with anorexia nervosa with varying levels of co-morbid depression and anxiety. In the second study, we found the same pattern of results in non-depressed individuals. In addition, use of first-person singular pronouns during negative memory recall was positively related to brooding (i.e. the assumed maladaptive sub-component of rumination but not to reflection. These findings could not be replicated in two samples of depressed patients. However, non-chronically depressed patients used more first-person singular pronouns than healthy controls, irrespective of context. Taken together, the findings lend partial support to theoretical models that emphasize the effects of context on self-focus and consider SFA as a relevant trans-diagnostic phenomenon. In addition, the present findings point to the construct validity of pronoun-use as a linguistic marker of maladaptive self-focus.

  5. Public health monitoring of developmental disabilities with a focus on the autism spectrum disorders.

    2004-02-15

    Developmental disabilities (DDs) are conditions characterized by physical, cognitive, psychological, sensory, adaptive, and/or communication impairments manifested during development. Approximately 17% of individuals in the United States 18 years and younger have a DD, and for most children the cause of their condition is unknown. Of particular interest are the autism spectrum disorders (ASDs), characterized by unusual social, communication, and behavioral development. Previously autism was thought to be a rare condition, but the number of children receiving services for an ASD has increased dramatically in the last decade. Concerns about increases in DDs, particularly ASDs, their causes, and the high costs of intervention have highlighted the need for systematic public health monitoring. Service provider data, such as annual reporting of special education services or of state DD programs, do not provide a complete estimate of the rates for DDs, including ASDs. Unlike genetic metabolic disorders or congenital hearing loss (HL) for which newborn screening programs can provide accurate prevalence rates, there are currently no genetic or biologic markers for the ASDs to enable consistent and early identification of affected children. Centers for Disease Control and Prevention's (CDC) Metropolitan Atlanta Developmental Disabilities Surveillance Program (MADDSP) is a model for population monitoring of ASDs/DDs that has been implemented in other states. This article discusses the role of ASD/DD tracking in public health, as well as the challenges of ASD/DD tracking, including case definition and identification, associated conditions, linkages, and data access.

  7. Looking Upstream: Findings from Focus Groups on Public Perceptions of Source Water Quality in British Columbia, Canada.

    Directory of Open Access Journals (Sweden)

    Natalie Henrich

    Full Text Available In association with the development of new microbial tests for source water quality (SWQ, focus groups with members of the public were conducted to gain insight into their perceptions of SWQ, behaviours and contaminants they think pose the greatest threat to its quality, and what/how they want to know about SWQ. Discussions revealed a low concern about SWQ in general, and in particular about microbial contamination. Participants identified behaviours that threaten SWQ, barriers to changing behaviour and suggestions for inducing change. A strong desire was expressed for water quality information to be interpreted and communicated in terms of how SWQ may impact human health and how their actions should be altered in response to test results. The information can be used to inform communication strategies and possibly impact policies associated with water quality testing and implementation of new tests. More broadly, awareness of the public's understanding and beliefs about source water can be used in working with the public to adopt water-friendly behaviours, influence the content and methods of communicating with the public about water issues and water quality, and could contribute to the direction of future research and investment into water technologies to align with the public's priorities.

    The present study used functional near-infrared spectroscopy (fNIRS) to measure 5- to 6-month-old infants' hemodynamic response in the prefrontal cortex (PFC) to visual stimuli differing in saliency and social value. Nineteen Japanese 5- to 6-month-old infants watched video clips of Peek-a-Boo (social signal) performed by an anime character (AC) or a human, and hand movements without social signal performed by an AC. The PFC activity of infants was measured by 22-channel fNIRS, while behaviors including looking time were recorded simultaneously. NIRS data showed that infants' hemodynamic responses in the PFC generally decreased due to these stimuli, and the decrease was most prominent in the frontopolar (FP), covering medial PFC (MPFC), when infants were viewing Peek-a-Boo performed by an AC. Moreover, the decrease was more pronounced in the dorsolateral PFC (DLPFC) when infants were viewing Peek-a-Boo performed by an AC than by a human. Accordingly, behavioral data revealed significantly longer looking times when Peek-a-Boo was performed by an AC than by a human. No significant difference between Peek-a-Boo and non-Peek-a-Boo conditions was observed in either measure. These findings indicate that infants at this age may prefer stimuli with more salient features, which may be more effective in attracting their attentions. In conjunction with our previous findings on responses to self-name calling in infants of similar age, we hypothesize that the dynamic function of the MPFC and its vicinity (as part of default mode network (DMN): enhanced by self-focused stimuli, attenuated by externally focused stimuli), which is consistently observed in adults, may have already emerged in 5- to 6-month-old infants.

    2013-12-01

    Full Text Available This paper aims at outlining a successful implementation of a project within LEADER framework, which is a local development method which allows local actors to develop an area by using its endogenous development potential. After a brief presentation of the characteristics of regional development strategies in Romania, there were emphasized the objectives and activities encompassed in a local development plan, managed by the leaders of the local action group called ‘Vrancea County’. In order to reinforce the strengths of Vrancea County and implicitly to assure a sustainable development of this area from the South-East part of Romania, a LAG constituted through a partnership between public and private actors settled a set of priorities to be exploited by means of specific actions. The goal of this paper is to highlight these priorities, by integrating them in a project management approach. The paper concludes with specifications about how Microsoft Project software could support project management initiatives that will be developed by the LAG Vrancea County in the next period.

    Sri Lanka is among the top ten countries in the world that report the highest rate of human rabies deaths (2.8 per 1,000,000 in 2007) and animal bites requiring anti-rabies post-exposure treatment (PET) (755 per 100,000 in 2003). Dogs are the main reservoir and transmitters of rabies in Sri Lanka. Present study evaluates the effectiveness of dog rabies control strategies on reducing incidence of human rabies deaths. Analysis is based on data from last three decades and showed strong correlations between the interventions and human rabies incidence. GIS maps provided a method for illustrating the district distribution of human rabies deaths and dog population density and for recognizing districts at risk. Interrupting the natural transmission cycle of rabies in dogs would be a logical approach in eliminating dog rabies in Sri Lanka. However, interventions implemented so far, such as dog vaccination, elimination of stray dogs (abandoned in 2005), and animal birth control have been inadequate to do so. Better understanding of the ecology of stray and owned dogs (e.g. population density, population structure, confinement status) in the context of the human environment and culture, are needed to strategize the control activities, requiring coordination among regional Public Health and Veterinary services.

    Full Text Available The intention of this paper is to analyze the lingering effects of the 2008 crisis in the United States and the implication they have on the policies undertaken by the Obama administration. A particular focus is given to the debt accumulation and how that relates to the challenges of the long run development of the American economy. The first part of this paper will give a brief overview of some of the elements central to the causes of the crisis, namely the centralization of wealth and its implication for the unsustainable consumption patterns. It will then follow to consider how the previous issues relate to the weak aggregate demand and the expansionary policies used to tackle it. Additionally, an overview of the crisis effect on the already troubled labor market is laid out in the third part. After exploring the interventionist policies used by the US administration in the after-crisis period, we move on to the presing issue of debt and possible scenarios that may arise in case it is not seriously addressed.

    Background Since 2010, federal and local agencies have invested broadly in a variety of nutrition-focused policy, systems and environmental change (PSE) initiatives in Los Angeles County (LAC). To date, little is known about whether the public supports such efforts. We address this gap in the literature by examining predictors of support for a variety of PSEs. Methods Voters residing in LAC (n=1007) were randomly selected to participate in a cross-sectional telephone survey commissioned by the LAC Department of Public Health. The survey asked questions about attitudes towards the obesity epidemic, nutrition knowledge and behaviours, public opinions about changing business practices/government policies related to nutrition, and sociodemographics. A factor analysis informed outcome variable selection (ie, type of PSEs). Multivariable regression analyses were performed to examine predictors of public support. Predictors in the regression models included (primary regressor) community economic hardship; (control variables) political affiliation, sex, age, race and income; and (independent variables) perceptions about obesity, perceived health and weight status, frequency reading nutrition labels, ease of finding healthy and unhealthy foods, and food consumption behaviours (ie, fruit and vegetables, non-diet soda, fast-food and sit-down restaurant meals). Results 3 types of PSE outcome variables were identified: promotional/incentivising, limiting/restrictive and business practices. Community economic hardship was not found to be a significant predictor of public support for any of the 3 PSE types. However, Republican party affiliation, being female and perceiving obesity as a serious health problem were. Conclusions These findings have implications for public health practice and community planning in local health jurisdictions. PMID:28087545

    Shared attention is extremely common. In stadiums, public squares, and private living rooms, people attend to the world with others. Humans do so across all sensory modalities-sharing the sights, sounds, tastes, smells, and textures of everyday life with one another. The potential for attending with others has grown considerably with the emergence of mass media technologies, which allow for the sharing of attention in the absence of physical co-presence. In the last several years, studies have begun to outline the conditions under which attending together is consequential for human memory, motivation, judgment, emotion, and behavior. Here, I advance a psychological theory of shared attention, defining its properties as a mental state and outlining its cognitive, affective, and behavioral consequences. I review empirical findings that are uniquely predicted by shared-attention theory and discuss the possibility of integrating shared-attention, social-facilitation, and social-loafing perspectives. Finally, I reflect on what shared-attention theory implies for living in the digital world.

    The article reported an in-depth comparative technology analysis of 1708 Anti-cancer patents from top 20 international universities and leading 10 Indian public funded organization and research institutes. The study segregated pioneer universities vs. technologies used in the field of Anticancer research at a level of drug discovery, development, diagnosis and treatment, which are illustrated in the form of novel substantive patent landscape maps. The reported competitive intelligent maps identified genetics, composition and synthetic compounds as dominating technologies; followed by natural extracts, combination and drug delivery systems as upcoming technologies. The least number of patents were reported by surgical apparatus, targeted therapy and animal models. In addition, the study analysed the key technologies followed by Indian universities in comparison to the international universities, to identify the overlooked technologies by the Indian public funded institutes. In an ever changing competitive world, it is essential for every university to have their own research plan and thrust areas; but at the same time, it is equally important for any organisation to have an idea of their competitor's research plan as well. So, the article suggested Indian institutes to focus on the latest emerging Anti-cancer technology trends, which are in practice by the international universities. Concurrently, this study may be a landmark indication for Indian public funded universities and institutes, calling for a U-turn from their traditional approaches.

Also it implies new kinds of attention (awareness) like when...... pupils try to listen to the teacher and simultaneously participate in online games. To this new social setting the teachers has reacted with either prohibition or unconcern. What has not been realised is that the introduction of new media profoundly challenges the way attention hitherto has functioned...... as a psychic prerequisite for the social interaction between pupils and teachers. New kinds of “split attention” arise and new kinds of social mediation (regulation and “use”) of psychic attention become necessary if teaching in the new digital medium milieu shall be beneficial.

    NHANES is the cornerstone for national nutrition monitoring to inform nutrition and health policy. Nutritional assessment in NHANES is described with a focus on dietary data collection, analysis, and uses in nutrition monitoring. NHANES has been collecting thorough data on diet, nutritional status, and chronic disease in cross-sectional surveys with nationally representative samples since the early 1970s. Continuous data collection began in 1999 with public data release in 2-y cycles on ∼10,000 participants. In 2002, the Continuing Survey of Food Intakes by Individuals and the NHANES dietary component were merged, forming a consolidated dietary data collection known as What We Eat in America; since then, 24-h recalls have been collected on 2 d using the USDA's Automated Multiple-Pass Method. Detailed and targeted food-frequency questionnaires have been collected in some NHANES cycles. Dietary supplement use data have been collected (in detail since 2007) so that total nutrient intakes can be described for the population. The continuous NHANES can adapt its content to address emerging public health needs and reflect federal priorities. Changes in data collection methods are made after expert input and validation/crossover studies. NHANES dietary data are used to describe intake of foods, nutrients, food groups, and dietary patterns by the US population and large sociodemographic groups to plan and evaluate nutrition programs and policies. Usual dietary intake distributions can be estimated after adjusting for day-to-day variation. NHANES remains open and flexible to incorporate improvements while maintaining data quality and providing timely data to track the nation's nutrition and health status. In summary, NHANES collects dietary data in the context of its broad, multipurpose goals; the strengths and limitations of these data are also discussed in this review.

    To review the recent research literature in clinical decision support systems (CDSS). A review of recent literature was undertaken, focussing on CDSS evaluation, consumers and public health, the impact of translational bioinformatics on CDSS design, and CDSS safety. In recent years, researchers have concentrated much less on the development of decision technologies, and have focussed more on the impact of CDSS in the clinical world. Recent work highlights that traditional process measures of CDSS effectiveness, such as document relevance are poor proxy measures for decision outcomes. Measuring the dynamics of decision making, for example via decision velocity, may produce a more accurate picture of effectiveness. Another trend is the broadening of user base for CDSS beyond front line clinicians. Consumers are now a major focus for biomedical informatics, as are public health officials, tasked with detecting and managing disease outbreaks at a health system, rather than individual patient level. Bioinformatics is also changing the nature of CDSS. Apart from personalisation of therapy recommendations, translational bioinformatics is creating new challenges in the interpretation of the meaning of genetic data. Finally, there is much recent interest in the safety and effectiveness of computerised physician order entry (CPOE) systems, given that prescribing and administration errors are a significant cause of morbidity and mortality. Of note, there is still much controversy surrounding the contention that poorly designed, implemented or used CDSS may actually lead to harm. CDSS research remains an active and evolving area of research, as CDSS penetrate more widely beyond their traditional domain into consumer decision support, and as decisions become more complex, for example by involving sequence level genetic data.

  11. A conceptual framework for selecting the most appropriate variables for measuring hospital efficiency with a focus on Iranian public hospitals.

    2009-05-01

    Over the past few decades, there has been an increasing interest in the measurement of hospital efficiency in developing countries and in Iran. While the choice of measurement methods in hospital efficiency assessment has been widely argued in the literature, few authors have offered a framework to specify variables that reflect different hospital functions, the quality of the process of care and the effectiveness of hospital services. However, without the knowledge of hospital objectives and all relevant functions, efficiency studies run the risk of making biased comparisons, particularly against hospitals that provide higher quality services requiring the use of more resources. Undertaking an in-depth investigation regarding the multi-product nature of hospitals, various hospital functions and the values of various stakeholders (patient, staff and community) with a focus on the Iranian public hospitals, this study has proposed a conceptual framework to select the most appropriate variables for measuring hospital efficiency using frontier-based techniques. This paper contributes to hospital efficiency studies by proposing a conceptual framework and incorporating a broader set of variables in Iran. This can enhance the validity of hospital efficiency studies using frontier-based methods in developing countries.

    In 2009, influenza A H1N1 caused the first pandemic of the 21st century. Although a vaccine against this influenza subtype was offered before or at the onset of the second epidemic wave that caused most of the fatal cases in Europe, vaccination rates for that season were lower than expected. We propose that the contradiction between high risk of infection and low use of available prevention measures represents a pandemic public health paradox. This research aims for a better understanding of this paradox by exploring the time-dependent interplay among changing influenza epidemiology, media attention, pandemic control measures, risk perception and public health behavior among five European countries (Czech Republic, Denmark, Germany, Spain and the UK). Findings suggest that asynchronicity between media curves and epidemiological curves may potentially explain the pandemic public health paradox; media attention for influenza A H1N1 in Europe declined long before the epidemic reached its peak, and public risk perceptions and behaviors may have followed media logic, rather than epidemiological logic.

    In public announcement logic it is assumed that all agents pay attention to the announcement. Weaker observational conditions can be modelled in action model logic. In this work, we propose a version of public announcement logic wherein it is encoded in the states of the epistemic model which...... agents pay attention to the announcement. This logic is called attention-based announcement logic. We give an axiomatization of the logic and prove that complexity of satisfiability is the same as that of public announcement logic, and therefore lower than that of action model logic. An attention......-based announcement can also be described as an action model. We extend our logic by integrating attention change. Finally, we add the notion of common belief to the language, we exploit this to formalize the concept of joint attention, that has been widely discussed in the philosophical and cognitive science...

  17. The Pennsylvania Experience with Hydraulic Fracturing for Shale Gas Development: Relatively Infrequent Water Quality Incidents with Lots of Public Attention

    Brantley, S. L.; Li, Z.; Yoxtheimer, D.; Vidic, R.

    2015-12-01

    New techniques of hydraulic fracturing - "fracking" - have changed the United States over the last 10 years into a leading producer of natural gas extraction from shale. The first such gas well in Pennsylvania was drilled and completed using high-volume hydraulic fracturing in 2004. By late 2014, more than 8500 of these gas wells had been drilled in the Marcellus Shale gas field in Pennsylvania alone. Almost 1000 public complaints about groundwater quality were logged by the PA Department of Environmental Protection (PA DEP) between 2008 and 2012. Only a fraction of these were attributed to unconventional gas development. The most common problem was gas migration into drinking water, but contamination incidents also included spills, seepage, or leaks of fracking fluids, brine salts, or very occasionally, radioactive species. Many problems of gas migration were from a few counties in the northeastern part of the state. However, sometimes one gas well contaminated multiple water wells. For example, one gas well was reported by the state regulator to have contaminated 18 water wells with methane near Dimock PA. It can be argued that such problems at a relatively small fraction of gas wells initiated pockets of pushback against fracking worldwide. This resistance to fracking has grown even though fracking has been in use in the U.S.A. since the 1940s. We have worked as part of an NSF-funded project (the Shale Network) to share water quality data and publish it online using the CUAHSI Hydrologic Information System. Sharing data has led to collaborative investigation of specific contamination incidents to understand how problems can occur, and to efforts to quantify the frequency of impacts. The Shale Network efforts have also highlighted the need for more transparency with water quality data in the arena related to the energy-water nexus. As more data are released, new techniques of data analysis will allow better understanding of how to tune best practices to be

    This article applies the phenomenological model of attention to plant monitoring of environmental stimuli and signal perception. Three complementary definitions of attention as selectivity, modulation and perdurance are explained with reference to plant signaling and behaviors, including foraging, ramet placement and abiotic stress communication. Elements of animal and human attentive attitudes are compared with plant attention at the levels of cognitive focus, context and margin. It is argued that the concept of attention holds the potential of becoming a cornerstone of plant intelligence studies.

  3. Sustainability Measures of Urban Public Transport in Cities: A World Review and Focus on the Asia/Middle East Region

    Directory of Open Access Journals (Sweden)

    Chris De Gruyter

    2016-12-01

    Full Text Available Previous studies of public transport sustainability in cities have been very limited to date, particularly in more developing countries located throughout Asia and the Middle East. This paper assesses the sustainability of urban public transport systems in cities by adopting a quantitative measurement framework containing 15 public transport sustainability indicators. It compares aggregate sustainability performance of urban public transport in international regions of cities, and then examines the relative sustainability of selected cities in the Asia and Middle East region. The world region analysis shows that Eastern Europe, Asia, and Latin America achieve the highest aggregate normalised scores for sustainable public transport, in that order. In general, the results suggest that western developed countries (Western Europe, North America, and Oceania have better performance on environmental and social indicators but poorer performance on system effectiveness and economic indicators. Asia and Latin America perform the other way round; better on economic and system effectiveness and worse on social and environmental indicators. Eastern Europe is one of the few regions with higher level performance all round. The city-based analysis of Asia/Middle East suggested that out of the 26 cities studied, the top 3 cities in terms of sustainable public transport in the Asia and Middle East Region are: 1st, Manila (Philippines; 2nd, Tokyo (Japan; and 3rd, Chennai (India.

    In a time when Europe is preparing to introduce new regulations on privacy protection, we conducted a survey among 1700 twins enrolled in the Italian Twin Register about the access and use of their medical records for public health research without explicit informed consent. A great majority of respondents would refuse or are doubtful about the access and use of hospital discharge records or clinical data without their explicit consent. Young and female individuals represent the modal profile of these careful people. As information retrieved from medical records is crucial for progressing knowledge, it is important to promote a better understanding of the value of public health research activities among the general population. Furthermore, public opinions are relevant to policy making, and concerns and preferences about privacy and confidentiality in research can contribute to the design of procedures to exploit medical records effectively and customize the protection of individuals' medical data. Significance for public healthInformation retrieved from medical records is critical for public health research and policy. In particular, large amounts of individual health data are needed in an epidemiological setting, where methodological constraints (e.g. follow-up update) and quality control procedures very often require data to be re-identifiable. Concern about European regulation affecting access to medical records seems to be widespread in the scientific community. Highlighting individuals' concerns and preferences about privacy and informed consent regarding the use of health data can support policy making for public health research. It can contribute to the design of procedures aiming to extract the greatest value from medical records and, more importantly, to create a system for the protection of personal data tailored to the needs of different people.

    A four-year college degree increases a student's employment prospects and earning potential. Given this importance, it is not surprising that 75 percent of Chicago Public Schools (CPS) high school students aspire to obtain at least a four-year college degree. Yet, prior research showed that few achieved this goal: a 2006 University of Chicago…

    Chronically understaffed public health laboratories depend on a decreasing number of employees who must assume broader responsibilities in order to sustain essential functions for the many clients the laboratories support. Prospective scientists considering a career in public health are often not aware of the requirements associated with working in a laboratory regulated by the Clinical Laboratory Improvement Amendments (CLIA). The purpose of this pilot internship was two-fold; introduce students to operations in a regulated laboratory early enough in their academics so that they could make good career decisions, and evaluate internship methodology as one possible solution to workforce shortages. Four interns were recruited from three different local universities, and were paired with an experienced State Laboratories Division (SLD) staff mentor. Students performed tasks that demonstrated the importance of CLIA regulations for 10-15 hours per week over a 14 week period. Students also attended several directed group sessions on regulatory lab practice and quality systems. Both interns and mentors were surveyed periodically during the semester. Surveys of mentors and interns indicated overall positive experiences. One-on-one pairing of experienced public health professionals and students seems to be a mutually beneficial arrangement. Interns reported that they would participate if the internship was lower paid, unpaid, or for credit only. The internship appeared to be an effective tool to expose students to employment in CLIA-regulated laboratories, and potentially help address public health laboratory staffing shortfalls. Longer term follow up with multiple classes of interns may provide a more informed assessment.

    A communication strategy was developed by The Consortium to Perform Human Biomonitoring on a European Scale (COPHES), as part of its objectives to develop a framework and protocols to enable the collection of comparable human biomonitoring data throughout Europe. The framework and protocols were tested in the pilot study DEMOCOPHES (Demonstration of a study to Coordinate and Perform Human biomonitoring on a European Scale). The aims of the communication strategy were to raise awareness of human biomonitoring, encourage participation in the study and to communicate the study results and their public health significance. It identified the audiences and key messages, documented the procedure for dissemination of results and was updated as the project progressed. A communication plan listed the tools and materials such as press releases, flyers, recruitment letters and information leaflets required for each audience with a time frame for releasing them. Public insight research was used to evaluate the recruitment material, and the feedback was used to improve the documents. Dissemination of results was coordinated in a step by step approach by the participating countries within DEMOCOPHES, taking into account specific national messages according to the needs of each country. Participants received individual results, unless they refused to be informed, along with guidance on what the results meant. The aggregate results and policy recommendations were then communicated to the general public and stakeholders, followed by dissemination at European level. Several lessons were learnt that may assist other future human biomonitoring studies. Recruitment took longer than anticipated and so social scientists, to help with community engagement, should be part of the research team from the start. As a European study, involving multiple countries, additional considerations were needed for the numerous organisations, different languages, cultures, policies and priorities

    This paper draws attention to food as a site around which a historically particular form of public engagement has emerged. In the past decade, some of the most lively debates and policy actions for science and publics have focused on food related issues: first with BSE and subsequently with genetically modified organisms. Even though much of the literature surrounding publics and science acknowledges that the very definition of "publics" is shifting, little attention has been paid to food as a significant arena in which publics are engaging in politically motivated challenges to techno-scientific practices, policies and institutions. Taking food seriously means contextualizing publics as well as extending discursive models of democratic engagement to embrace consumer practices.

    Overweight prevalence among Guatemalan girls is higher in public than in private schools. Little is known about adolescent girls' perceptions of the right ways to achieve a healthy weight. This study examines public and private school adolescent girls' perceptions of a "healthy weight," and barriers and facilitators to achieving it. We conducted 4 focus groups in public and private schools in Guatemala City with girls from 13 to 15 years old. The discussion guide included open-ended questions and activities aimed at examining perceptions of "healthy weight" and barriers and motivators to achieving it within the school environment. Focus groups were audio-recorded and transcribed. Data analyses followed established methods of content analysis. Twenty-eight girls (private school, n = 12; public school, n = 16) of ages ranging from 13.1 to 15.9 years (median, 14, IQR, 13.6-14.9) participated in the study. Girls identified images of thin and fit women as healthy. They cited healthy eating and physical activity as ways to achieve a healthy weight. Within the school environment, barriers to maintaining a healthy weight included a lack of healthy food options and the prioritization of sports for boys over girls. In public schools, facilities were less than optimal; in private schools, girls' access to facilities was limited. Public school girls stated that their uniforms were inappropriate for exercising. Our findings support the need to provide more healthy food options in Guatemalan schools. In addition, physical activity for girls should be promoted and facilities made available for their use.

    Many seismic events are only picked up by seismometers but the only earthquakes that really interest the public (and the authorities) are those which are felt by the population. It is not a magnitude issue only; even a small magnitude earthquake, if widely felt can create a public desire for information. In LastQuake, felt events are automatically discriminated through the reactions of the population on the Internet. It uses three different and complementary methods. Twitter Earthquake detection, initially developed by the USGS, detects surges in the number of tweets containing the word "earthquake" in different languages. Flashsourcing, developed by EMSC, detects traffic surges caused by eyewitnesses on its website - one of the top global earthquake information websites. Both detections happen typically within 2 minutes of an event's occurrence. Finally, an earthquake is also confirmed as being felt when at least 3 independent felt reports (questionnaires) are collected. LastQuake automatically merges seismic data, direct (crowdsourced) and indirect eyewitnesses' contributions, damage scenarios and tsunami alerts to provide information on felt earthquakes and their effects in a time ranging from a few tens of seconds to 90 minutes. It is based on visual communication to erase language hurdles, for instance, it crowdsources felt reports through simple cartoons as well as geo-located pics. It was massively adopted in Nepal within hours of the Gorkha earthquake and collected thousands of felt reports and more than 100 informative pics. LastQuake is also a seismic risk reduction tools thanks to its very rapid information. When such information does not exist, people tend to call emergency services, crowds emerge and rumors spread. In its next release, LastQuake will also have "do/don't do" cartoons popping up after an earthquake to encourage appropriate behavior.

    The aim of the present study was to assess mental flexibility and set maintenance of a group of individuals with Asperger syndrome (AS) or high-functioning autism (HFA) (N = 13; mean age 16,4), as compared with a matched group of typically developing children and adolescents (N = 13; mean age 15,6) on the computerized version of the Wisconsin Card Sorting Test (WCST). The participants in the AS/HFA group performed less well than the controls on all categories of the WCST, but the differences did not reach conventional statistical significance on most categories of the WCST. On the category failure to maintain set, however, the AS/HFA participants performed significantly less well than the controls, suggesting a deficit of focused attention.

    As influenza H1N1 spreads around the world, health officials are considering the development and use of a new vaccine to protect the public and help control the outbreak. Acceptance of novel vaccines during health crises, however, is influenced by perceptions of a range of risks, including the risk of infection, risk of becoming severely ill or dying if infected, as well as the risk of serious side and long-term effects of the vaccine. A study on 11 focus groups was conducted with the public in Vancouver, Canada in 2006 and 2007 to explore how people assess these risks and how these assessments relate to their willingness to use novel vaccines in a pandemic. Concerns about using new vaccines during a pandemic differ from concerns about using established products in a non-crisis situation. Participants were hesitant to use novel vaccines because of a low perception of the early risk of infection in a pandemic, coupled with the many uncertainties that surround new vaccines and the emerging infectious disease, and owing to the concern that unsafe pharmaceuticals may be rushed to market during a health crisis. Understanding the public´s assessment of the risks related to, and willingness to use, novel vaccines during a pandemic can help officials promote disease-control measures in ways that improve the likelihood of acceptance by the public and may increase uptake of an H1N1 vaccine.

    There is an urgent need to establish effective strategies for suicide prevention. Stigma against depression may be a potential anti-protective factor for suicide. Thus, we investigated baseline levels of awareness and attitudes toward depression and its treatment among the general population by our original 18-item questionnaire, which we aimed to validate in the present study. Next, we conducted two types of educational interventions and examined the results to clarify the difference in the quality of these lectures. Subjects were 834 citizens (245 males and 589 females) who received an anti-stigma-targeted (n = 467) or non-targeted lecture (n = 367). An 18-item questionnaire assessing levels of awareness and attitudes toward depression and its treatments was administered to each participant before and after the lecture. A chi-square test was used to investigate categorical variables for background data on the participants. Factor analysis of baseline scores was conducted on the 18 questionnaire items. Student's t-test was used for analysis of the gender effect. A two-way analysis of variance (ANOVA) was used for comparison among the 5 age groups and comparison of the effect of the two lectures. Multiple regression analysis was applied to examine the determinants of improved attitudes after intervention. Public attitudes toward depression consisted of 4 distinct elements, which were disease-model attitudes, help-seeking behavior, negative affect toward depression, and non-medication solutions. Older participants had poorer disease-model attitudes and more negative affect toward depression, whereas younger participants showed poorer help-seeking behavior (p lecture was superior to the non-targeted lecture in improving disease-model attitudes and non-medication solutions (p lecture was strongly dependent on its own baseline subscale score (p lecture scores on negative affect toward depression and non-medication solutions (p < 0.01).

    Full Text Available Informal inhabitances as part of urban decay texture are regarded as one of the most important urban challenges of Iran and have caused disorder in the urban space from viewpoint of construction and function; which requires serious attention of urban management for organizing with different approaches and public partnership. One of the suitable approaches for intervention in these textures is enablement that involves increase of using inner potentials of urban societies for administering public and social affairs; which leads to stability of process of development. Enablement is mainly in the way of spatial organizing of informal textures and actions beyond frame aspects; which requires partnership of all deprived classes of society for obtaining to trustworthiness, creating institution and potentials for local associations. Attracting the trust of people is necessary issue for developing partnership and partnership offers ability of promotion, education of low-income classes of society and connects them to society. Using the method of partnership for enabling such inhabitances involves people in the process of design, utilization and execution. The present research through defining different aspects of partnership, examines the solutions for increasing public partnership of inhabitants of Islamabad area of Karaj in compliance with enablement approach and thus, upon determining the operational model of research that consists of items of partnership and enablement, the level of partnership of people in the area of our study is examined. Research findings reveal that level of partnership of inhabitants is very low; thus, in the way of solving the problem of informal inhabitances of Islamabad, first of all by using suitable methods, it is necessary for improving the enablement of people at different levels and then to except the level of partnership of inhabitants may be increased.

    Studies of human attention dynamics analyses how attention is focused on specific topics, issues or people. In online social media, there are clear signs of exogenous shocks, bursty dynamics, and an exponential or powerlaw lifetime distribution. We here analyse the attention dynamics of traditional media, focussing on co-occurrence of people in newspaper articles. The results are quite different from online social networks and attention. Different regimes seem to be operating at two different time scales. At short time scales we see evidence of bursty dynamics and fast decaying edge lifetimes and attention. This behaviour disappears for longer time scales, and in that regime we find Poissonian dynamics and slower decaying lifetimes. We propose that a cascading Poisson process may take place, with issues arising at a constant rate over a long time scale, and faster dynamics at a shorter time scale.

    2004-01-01

    Some medical providers have advocated applied genomics, including the use of genetically linked racial phenotypes in medical practice, raising fear that race-based medication will become justified. As with other emerging medical genetic technologies, pharmaceutical companies may advertise these treatments. Researchers fear that consumers will uncritically accept pharmaceutical messages and demand the product. In this exploratory study, we examined public reactions to advertisements for applied genomic medications. A focus group methodology was employed. Participants tended to resist the message and generated warrants for doing so, indicating critical reception of the messages. Message accepters also provided warrants. Warrants for resistance and acceptance differ between self-identified racial groups. Consumers, health care providers, and pharmaceutical corporations will benefit from a better understanding of direct-to-consumer advertisements as medical communication. Our study concludes that both advocates and opponents of direct-to-consumer advertisements should recognize that potential consumers of pharmacogenomics act as critical consumers of health advertising discourse.

  6. Public knowledge and public trust.

    As health care applications derived from human genetics research are likely to move increasingly from 'clinic to community', there is growing interest not just in how patients understand and take up health-related genetic information but also in the views of the wider population, as well as a range of professional groups. In this paper, issues relating public knowledge and public trust are raised and discussed in an attempt to move forward debates about public involvement in genomic research and the role of sociologists within interdisciplinary teams. As the field of public understanding of science has developed, we have seen a shift from a focus on the lack of scientific literacy as problem to a recognition of the range of different knowledges that people have and use as they confront science and technology in their everyday lives. As a mood for dialogue pervades many institutions in their relations with 'publics', attention must now be paid to the way in which knowledge and expertise is expressed, heard and acted upon in dialogic encounters. There is increasing concern about public trust in science and calls to increase public confidence, particularly through more open engagement with a range of publics. However, lack of trust or loss of confidence may be constructed as problems rather than reflecting empirical reality, where more complex relationships and attitudes prevail. Lack of trust is often privatized, deeply rooted in lived experience and routinely managed. Trust relations are generally characterized by ambivalence, uncertainty and risk, and are always provisional. Drawing on selected literature and empirical research to review and illustrate this field, this paper argues that scepticism or ambivalence on the part of publics are not necessarily problems to be overcome in the interest of scientific progress, but rather should be mobilized to enhance open and public debates about the nature and direction of genomics research, medicine, and the related

    Full Text Available Abstract Background UK drinkers regularly consume alcohol in excess of guideline limits. One reason for this may be the high availability of low-cost alcoholic beverages. The introduction of a minimum price per unit of alcohol policy has been proposed as a means to reduce UK alcohol consumption. However, there is little in-depth research investigating public attitudes and beliefs regarding a minimum pricing policy. The aim of the present research was to investigate people’s attitudes and beliefs toward the introduction of a minimum price per unit of alcohol policy and their views on how the policy could be made acceptable to the general public. Methods Twenty-eight focus groups were conducted to gain in-depth data on attitudes, knowledge, and beliefs regarding the introduction of a minimum price per unit of alcohol policy. Participants (total N = 218 were asked to give their opinions about the policy, its possible outcomes, and how its introduction might be made more acceptable. Transcribed focus-group discussions were analysed for emergent themes using inductive thematic content analysis. Results Analysis indicated that participants’ objections to a minimum price had three main themes: (1 scepticism of minimum pricing as an effective means to reduce harmful alcohol consumption; (2 a dislike of the policy for a number of reasons (e.g., it was perceived to ‘punish’ the moderate drinker; and (3 concern that the policy might create or exacerbate existing social problems. There was a general perception that the policy was aimed at ‘problem’ and underage drinkers. Participants expressed some qualified support for the policy but stated that it would only work as part of a wider campaign including other educational elements. Conclusions There was little evidence to suggest that people would support the introduction of a minimum price per unit of alcohol policy. Scepticism about the effectiveness of the policy is likely to represent the most

    Background Physiotherapy research concerning interventions for children with CP is often focused on collecting evidence of the superiority of particular therapeutic methods or treatment modalities. Articulating and documenting the use of theory, instrumentation and research design and the assumptions underlying physiotherapy research interventions are important. Physiotherapy interventions focusing on children with Cerebral Palsy should, according to the literature, be based on a functional and environmental perspective with task-specific functional activity, motor learning processes and Family-Centred Service i.e. to enhance motor ability and improve capacity so that the child can perform the tasks necessary to participate actively in everyday life. Thus, it is important to coordinate the norms and values of the physiotherapist with those of the family and child. The aim of this study was to describe how physiotherapists’ experiences physiotherapy interventions for children with CP in scientific physiotherapy publications written by physiotherapists. Methods A qualitative phenomenographic approach was used. Twenty- one scientific articles, found in PubMed, strategically chosen according to year of publication (2001–2009), modality, journals and country, were investigated.

    2012-12-01

    In the past two decades, there has been an increased interest in the assessment and treatment of preschool children presenting with concerns about attention problems. This article reviews the research and clinical literature involving assessment of attention and related skills in the preschool years. While inattention among preschoolers is common, symptoms alone do not necessarily indicate a disorder, and most often represent a normal variation in typical preschool child development. Thus, accurate identification of "disordered" attention in preschoolers can be challenging, and development of appropriate, norm-referenced tests of attention for preschoolers is also difficult. The current review suggests that comprehensive assessment of attention and related functions in the preschool child should include thorough review of the child's history, planned observations, and formal psychometric testing. The three primary methods of psychometric assessment that have been used to characterize attentional functioning in preschool children include performance-based tests, structured caregiver interviews, and rating scales (parent, teacher, and clinician). Among performance-based methods for measurement of attention in the preschool years, tests have been developed to assess sustained attention, selective (focused) attention, span of attention (encoding/manipulation), and (top-down) controlled attention--including freedom from distractibility and set shifting. Many of these tests remain experimental in nature, and review of published methods yields relatively few commercially available, nationally normed tests of attention for preschoolers, and an overall dearth of reliability and validity studies on the available measures.

    2012-11-01

    Changes in sustained attention, attentional selectivity, and attentional capacity were examined in a sample of 113 participants between the ages of 12 and 75. To measure sustained attention, we employed the sustained-attention-to-response task (Robertson, Manly, Andrade, Baddeley, & Yiend, Neuropsychologia 35:747-58, 1997), a short continuous-performance test designed to capture fluctuations in sustained attention. To measure attentional selectivity and capacity, we employed a paradigm based on the theory of visual attention (Bundesen, Psychological Review 97:523-547, 1990), which enabled the estimation of parameters related to attentional selection, perceptual threshold, visual short-term memory capacity, and processing capacity. We found evidence of age-related decline in each of the measured variables, but the declines varied markedly in terms of magnitude and lifespan trajectory. Variables relating to attentional capacity showed declines of very large effect sizes, while variables relating to attentional selectivity and sustained attention showed declines of medium to large effect sizes, suggesting that attentional control is relatively preserved in older adults. The variables relating to sustained attention followed a U-shaped, curvilinear trend, and the variables relating to attentional selectivity and capacity showed linear decline from early adulthood, providing further support for the differentiation of attentional functions.

    This review focuses on covert attention and how it alters early vision. I explain why attention is considered a selective process, the constructs of covert attention, spatial endogenous and exogenous attention, and feature-based attention. I explain how in the last 25 years research on attention has characterized the effects of covert attention on spatial filters and how attention influences the selection of stimuli of interest. This review includes the effects of spatial attention on discriminability and appearance in tasks mediated by contrast sensitivity and spatial resolution; the effects of feature-based attention on basic visual processes, and a comparison of the effects of spatial and feature-based attention. The emphasis of this review is on psychophysical studies, but relevant electrophysiological and neuroimaging studies and models regarding how and where neuronal responses are modulated are also discussed.

  7. Combining segmentation and attention: a new foveal attention model

    Rebeca eMarfil

    2014-08-01

    Full Text Available Artificial vision systems cannot process all the information that they receive from the world in real time because it is highly expensive and inefficient in terms of computational cost. Inspired by biological perception systems, articial attention models pursuit to select only the relevant part of the scene. Besides, it is well established that the units of attention on human vision are not merely spatial but closely related to perceptual objects (proto-objects. This implies a strong bidirectional relationship between segmentation and attention processes. Therefore, while the segmentation process is the responsible to extract the proto-objects from the scene, attention can guide segmentation, arising the concept of foveal attention. When the focus of attention is deployed from one visual unit to another, the rest of the scene is perceived but at a lower resolution that the focused object. The result is a multi-resolution visual perception in which the fovea, a dimple on the central retina, provides the highest resolution vision. In this paper, a bottom-up foveal attention model is presented. In this model the input image is a foveal image represented using a Cartesian Foveal Geometry (CFG, which encodes the field of view of the sensor as a fovea (placed in the focus of attention surrounded by a set of concentric rings with decreasing resolution. Then multirresolution perceptual segmentation is performed by building a foveal polygon using the Bounded Irregular Pyramid (BIP. Bottom-up attention is enclosed in the same structure, allowing to set the fovea over the most salient image proto-object. Saliency is computed as a linear combination of multiple low level features such us colour and intensity contrast, symmetry, orientation and roundness. Obtained results from natural images show that the performance of the combination of hierarchical foveal segmentation and saliency estimation is good in terms of accuracy and speed.

    This article explores ethical considerations related to participatory visual and digital methods for public health research and practice, through the lens of an approach known as "digital storytelling." We begin by briefly describing the digital storytelling process and its applications to public health research and practice. Next, we explore 6 common challenges: fuzzy boundaries, recruitment and consent to participate, power of shaping, representation and harm, confidentiality, and release of materials. We discuss their complexities and offer some considerations for ethical practice. We hope this article serves as a catalyst for expanded dialogue about the need for high standards of integrity and a situated practice of ethics wherein researchers and practitioners reflexively consider ethical decision-making as part of the ongoing work of public health.

  9. Attention decay in science

    Parolo, Pietro Della Briotta; Ghosh, Rumi; Huberman, Bernardo A; Kaski, Kimmo; Fortunato, Santo

    2015-01-01

    The exponential growth in the number of scientific papers makes it increasingly difficult for researchers to keep track of all the publications relevant to their work. Consequently, the attention that can be devoted to individual papers, measured by their citation counts, is bound to decay rapidly. In this work we make a thorough study of the life-cycle of papers in different disciplines. Typically, the citation rate of a paper increases up to a few years after its publication, reaches a peak and then decreases rapidly. This decay can be described by an exponential or a power law behavior, as in ultradiffusive processes, with exponential fitting better than power law for the majority of cases. The decay is also becoming faster over the years, signaling that nowadays papers are forgotten more quickly. However, when time is counted in terms of the number of published papers, the rate of decay of citations is fairly independent of the period considered. This indicates that the attention of scholars depends on th...

    For 20 years, the Ministry of Health, Labour and Welfare (MHLW, formerly Ministry of Health and Welfare (MHW)) has been trying to increase transparency of the review process for approving reports in order to promote the rational use of newly approved drugs and medical devices. The first Summary Basis of Approval (SBA) was published by MHW in 1994. In 1999, evaluation reports were prepared by MHW and the Pharmaceuticals and Medical Devices Evaluation Center to make them available to the public. In 2005, a notice from the Chief Executive of the Pharmaceuticals and Medical Devices Agency (PMDA) made procedures for public release of information on reviewing applications for new drugs. In 2006, 90 review reports of newly approved drugs and eight medical devices were revealed on PMDA websites. The dissemination of information by the United States Food and Drug Administration (FDA) and that of the European Medicines Agency (EMA) were studied and compared with that of the MHLW and PMDA. While common technical documents (CTD) for new drugs and summary technical documents (STED) for new medical devices have been released by PMDA, such documents are not released by the FDA and EMA. The European Public Assessment Report (EAPR) summary for the public is an interesting questionnaire approach that uses the "What," "How" and "Why" format. Finally, future proposals for the next decade are also outlined.

    When a global moving pattern is superimposed on high-contrast stationary or slowly moving stimuli,the stimuli can be perceived as disappearing and reappearing alternately for periods of several seconds. This visual illusory phenomenon was named "motion-induced blindness" (MIB) in recent literature. So far there is no consensus on the mechanism of MIB, especially on the role of attention in this phenomenon. To examine the effect of spatial attention on MIB, the present study manipulated the participants' spatial attention by asking them to respond to two targets simultaneously presented in bilateral visual fields (the divided-attention condition) or only respond to one of them (the focused-attention condition). A central arrow was presented as an endogenous cue to index the target visual field in the focused-attention condition, while a point was presented instead in the divided-attention condition. The results show that the percentage of accumulated invisibility period was larger for the targets in the focused-attention condition than for those in the divided-attention condition.This effect of attentionis significant in upper visual field (UVF) and left lower visual field (left LVF); that is, this effect shows a hemispheric asymmetry in LVF but not in UVF. Furthermore, the percentage of accumulated invisibility period was larger for targets in left LVF than for those in right LVF in the focused-attention condition, but no hemispheric asymmetry was found in the divided-attention condition.In addition, the increased percentage of accumulated invisibility period in the focused-attention condition originated merely in the enhancement of the mean phase duration of disappearance in LVF, while the disappearance occurred more frequently and lasted longer for each occurrence, which led to an increase in the total invisibility period, in the focused- than divided-attention condition in UVF. These results suggest that the modulation of spatial attention on MIB has different

    : For parenting programs to achieve a public health impact, it is necessary to develop more effective marketing strategies to increase public awareness of these programs and promote parental participation. In this article, we compared a promotion-focused and a prevention-focused strategy via two studies. : We designed two ads inviting parents to participate in a universal parenting program; one ad focused on the program increasing the likelihood of positive outcomes for children (promotion-focused) and the other on the program reducing the likelihood of negative outcomes (prevention-focused). In study I, the two ads were run online simultaneously. Those who clicked on an ad were directed to a website where they could read about and sign up for the program. In study II, a community sample of 706 parents answered a questionnaire about the ads. : In study I, over 85 days, the prevention ad generated more clicks. There was no difference in the number of pages visited on the website nor in the number of parents who signed up for the program. In study II, parents showed a preference for the promotion ad, perceiving it as more relevant and rating it as more effective in getting them interested in the program. : A prevention strategy may be more effective in drawing public attention, in general. However, a promotion strategy is more likely to reach parents, in particular, and inspire them to consider participating in parenting programs. These strategies should be developed further and tested in both general and clinical populations.

    We examine whether attention deficits underlie developmental dyslexia, or certain types of dyslexia, by presenting double dissociations between the two. We took into account the existence of distinct types of dyslexia and of attention deficits, and focused on dyslexias that may be thought to have an attentional basis: letter position dyslexia (LPD), in which letters migrate within words, attentional dyslexia (AD), in which letters migrate between words, neglect dyslexia, in which letters on o...

    传统研究中,品牌承诺被认为是消费者抵御品牌负面信息的关键,高承诺消费者的品牌态度不易受到负面信息的影响。然而实验表明,这一过程会受到自我调节导向的调节:当消费者处于促进型调节导向的时候,低承诺消费者的品牌态度显著下降,而高承诺消费者的品牌态度不受影响;当消费者处于防御调节导向的时候,无论其品牌承诺高低,品牌态度均会受到负面信息的影响。这是因为处于防御调节导向的时候,高品牌承诺消费者的态度保护动机受到抑制,难以对品牌负面信息产生抵抗作用。研究还发现促进型调节导向的消费者较防御型调节导向的消费者更不容易受到品牌负面信息的影响。%In previous research, brand commitment is regarded as the key factor for consumers to resist negative publicity, scholars generally agree that consumers who have high brand commitment are less likely to change their brand attitudes when they are exposed to the brand’s negative publicity. But this is not always the case, evidence shows that some of the high commitment consumers also lower their brand attitudes and even drop their purchasing behavior when facing the brand’s negative publicity. Thus, It is reasonable to infer that the effect of brand commitment on consumers’ responses to negative publicity could be dependent on certain conditions instead of linear. Based on the regulatory focus theory, this study examines whether regulatory focus can moderate the high commitment consumers’ resistance to the negative publicity. Two studies were conducted to test the hypotheses that when consumers in prevention focus, no matter how high their brand commitment was, their brand attitudes would be lowered by the negative publicity;While when consumers in promotion focus, the low commitment consumers’ attitudes would be lowered and the high commitment consumers’ attitudes would remain

    2015-06-01

    There is a lack of comparative effectiveness research among attention deficit hyperactivity disorder (ADHD) drugs in terms of efficacy and acceptability, where bupropion is compared with atomoxetine, lisdexamfetamine and methylphenidate. The main aim of this work was to compare the efficacy and acceptability of these drugs in children and adolescents using a metaanalysis. A literature search was conducted to identify double-blind, placebo-controlled, noncrossover studies of ADHD. PubMed/Medline and Clinicaltrials.gov were searched. Comparative drug efficacy to placebo was calculated based on the standardized mean difference (SMD), while the comparative drug acceptability (all cause discontinuation) to placebo was estimated on the odds ratio (OR). In total 28 trials were included in the meta-analysis. Efficacy in reducing ADHD symptoms compared to placebo was small for bupropion (SMD=-0.32, 95% CI; -0.69, 0.05), while modest efficacy was shown for atomoxetine (SMD=-0.68, 95% CI; -0.76, -0.59) and methylphenidate (SMD=-0.75, 95% CI; -0.98, -0.52) and high efficacy was observed for lisdexamfetamine (SMD=-1.28, 95% CI; -1.84, -0.71). Compared to placebo treatment discontinuation was statistically significantly lower for methylphenidate (OR=0.35, 95% CI; 0.24, 0.52), while it was not significantly different for atomoxetine (OR=0.91, 95% CI; 0.66, 1.24), lisdexamfetamine (OR=0.60, 95% CI, 0.22, 1.65), and bupropion (OR=1.64, 95% CI; 0.5, 5.43). The heterogeneity was high, except in atomoxetine trials. The crossover studies were excluded. The effect sizes at specific time points were not computed. Studies with comorbid conditions, except those reporting on oppositional defiant disorder, were also excluded. All studies involving MPH were combined. The results suggest that lisdexamfetamine has the best benefit risk balance and has promising potential for treating children and adolescents with ADHD. More research is needed for a better clinical evaluation of bupropion

    This research provides experimental evidence for cultural influence on one of the most basic elements of emotional processing: attention to positive versus negative stimuli. To this end, we focused on Russian culture, which is characterized by brooding and melancholy. In Study 1, Russians spent significantly more time looking at negative than positive pictures, whereas Americans did not show this tendency. In Study 2, Russian Latvians were randomly primed with symbols of each culture, after which we measured the speed of recognition for positive versus negative trait words. Biculturals were significantly faster in recognizing negative words (as compared with baseline) when primed with Russian versus Latvian cultural symbols. Greater identification with Russian culture facilitated this effect. We provide a theoretical discussion of mental processes underlying cultural differences in emotion research.

  9. Cold-Blooded Attention: Finger Temperature Predicts Attentional Performance

    2017-09-01

    Full Text Available Thermal stress has been shown to increase the chances of unsafe behavior during industrial and driving performances due to reductions in mental and attentional resources. Nonetheless, establishing appropriate safety standards regarding environmental temperature has been a major problem, as modulations are also be affected by the task type, complexity, workload, duration, and previous experience with the task. To bypass this attentional and thermoregulatory problem, we focused on the body rather than environmental temperature. Specifically, we measured tympanic, forehead, finger and environmental temperatures accompanied by a battery of attentional tasks. We considered a 10 min baseline period wherein subjects were instructed to sit and relax, followed by three attentional tasks: a continuous performance task (CPT, a flanker task (FT and a counting task (CT. Using multiple linear regression models, we evaluated which variable(s were the best predictors of performance. The results showed a decrement in finger temperature due to instruction and task engagement that was absent when the subject was instructed to relax. No changes were observed in tympanic or forehead temperatures, while the environmental temperature remained almost constant for each subject. Specifically, the magnitude of the change in finger temperature was the best predictor of performance in all three attentional tasks. The results presented here suggest that finger temperature can be used as a predictor of alertness, as it predicted performance in attentional tasks better than environmental temperature. These findings strongly support that peripheral temperature can be used as a tool to prevent unsafe behaviors and accidents.

  10. Management challenges at the intersection of public policy environments and strategic decision making in public hospitals.

    Longest, Beaufort B

    2012-01-01

    Hospitals in the United States are heavily impacted by public policies that affect them. For example, Medicare and Medicaid programs account for more than half the revenue in most of the nation's almost 5,000 community hospitals, including the almost 1,100 public hospitals controlled by state and local governments (American Hospital Association, 2012). The public hospitals are especially closely aligned with and controlled by governmental entities compared with hospitals with other kinds of sponsorship. This article addresses the management challenges at the intersection of the strategic management of public hospitals and their public policy environments. Public hospitals are complicated entities designed not only to provide health services but also in many cases to play key roles in health-related research and education and to play important general economic development roles in their communities. The multi-faceted strategic decision making in these organizations is as heavily affected by their public policy environments as by their business, demographic, technological or other external environments. Effectively managing the intersection of their public policy environments and their strategic management is indeed vital for contemporary public hospitals. This article is intended to clarify certain aspects of this intersection through a description and model of the strategic activity in public hospitals and the connection between this activity and their external environments. Specific attention is focused on the concept of public policy environments and their features. Attention is also given to how managers can assess public policy environments and incorporate the results into strategic activities.

    The data on the top 20 journals in the Science Citation Index(Expanded) for 10 years from 2005 to 2014 indicated the first and second positions for Korean papers were occupied by the Korean journals, which implied the need for globalization of target journals to publish Korean papers. Further study is required for comparative analysis of the factors impacting on the number of papers and citations, which is the criteria for quality evaluation of papers, in other area than the Nuclear Energy and Engineering to which this study was limited. As the media for research process and results, papers play an important role in the evaluation of research projects. While the traditional methods for evaluation of research results have been focused on quantity aspects, the implication of quality aspect is increasingly recognized. Most national labs have begun to shift from quantity to quality in their criteria for overall evaluation of research results. It is therefore desired to maximize the quality level of the research papers for which the trends in citation as quality indicator could be analyzed as well as the quantity aspect. This paper looks at the trends in the number of citation and papers as the indicators of quality and quantify, as drawn from Scopus Data Base. It also suggest top 5 Science Citation Index(Expanded) journals in terms of increase rate in both number of papers and citations. The purpose is to compare them with top 20 Science Citation Index(Expanded) journals in which Korea Atomic Energy Research researchers have published their papers in the past 10 years from 2005 to 2014 were submitted. This paper looked at the trends in the number of papers and citations as an indicator of quality of the research papers in the area of Nuclear Energy and Engineering which is in fact a limitation to the key subject area, not covering the whole nuclear science and technology.

    Due to a worldwide increase in overweight and obesity, weight-management through lifestyle changes has become an important public health issue. Adolescents and young adults comprise a vulnerable group. The transition into adulthood represents a stage in life when establishing good lifestyle habits for the future is important. The aim of this study was to explore motivation and obstacles for weight reduction, weight maintenance and healthy lifestyle choices in young women. We conducted semi-structured in depth interviews with 12 young women, both overweight and normal weight, recruited from a school-based population survey. By the use of thematic analysis we searched the interview text for relevant meaning units that emerged as topics that illuminated our research questions. A strong motivation for obtaining or keeping normal weight was clearly present among the participants. Independent of weight-group, the participants described increased levels of physical activity, better eating habits and regularity in daily life as desirable changes. Parents were described as important influencers regarding lifestyle habits. Several participants expressed a need for more information about healthy nutrition and eating. Their motivation for physical activity depended on a positive social setting and elements of joy. The participants described the transition into adulthood including moving out of their parents' home and other structural changes in everyday life, as challenging. It affected their food choices and eating habits and other lifestyle issues. High costs of healthy food and sports activities were frequently mentioned among the obstacles they encountered. The results revealed an obvious motivation for lifestyle changes in individuals and environmental challenges for young women in the relevant stage of their life-course. There seems to be a need for health strategies that strengthens individuals' capacity to overcome the environmental challenges in the transition to

  13. How to keep attention from straying: get engaged!

    Science.gov (United States)

    Folk, Charles L; Ester, Edward F; Troemel, Kristof

    2009-02-01

    Previous research has suggested that the involuntary allocation of spatial attention to salient, irrelevant stimuli (i.e., attentional capture) is prevented when attention is in a focused state (e.g., Yantis & Jonides, 1990). Recent work has suggested that although focused attention may be necessary to prevent attentional capture by irrelevant stimuli, it is not sufficient (e.g., Folk, Leber, & Egeth, 2002). The present experiments provide evidence that attentional engagement, rather than attentional focusing, prevents capture. Observers performed a rapid serial visual presentation task in which they were asked to identify a target letter defined by color. Peripheral distractors that shared the color of the target produced evidence of attentional capture. This effect was completely eliminated, however, when the peripheral distractor was preceded by a central distractor designed to engage attention on the stream. It is concluded that attentional engagement serves to lock out capture by irrelevant, salient stimuli.

  16. When attention wanders: Pupillometric signatures of fluctuations in external attention.

    2017-11-01

    Attention is not always directed to events in the external environment. On occasion our thoughts wander to people and places distant from the here and now. Sometimes, this lack of external attention can compromise ongoing task performance. In the current study we set out to understand the extent to which states of internal and external attention can be determined using pupillometry as an index of ongoing cognition. In two experiments we found that periods of slow responding were associated with elevations in the baseline pupil signal over three and a half seconds prior to a behavioural response. In the second experiment we found that unlike behavioural lapses, states of off-task thought, particularly those associated with a focus on the past and with an intrusive quality, were associated with reductions in the size of the pupil over the same window prior to the probe. These data show that both states of large and small baseline pupil size are linked to states when attention is not effectively focused on the external environment, although these states have different qualities. More generally, these findings illustrate that subjective and objective markers of task performance may not be equivalent and underscore the importance of developing objective indicators that can allow these different states to be understood.

    2012-02-01

    Improvements in attentional performance are at the core of proposed mechanisms for stress reduction in mindfulness meditation practices. However, this claim can be questioned because no previous studies have actively manipulated test effort in control groups and controlled for effects of stress reduction per se. In a blinded design, 48 young, healthy meditation novices were randomly assigned to a mindfulness-based stress reduction (MBSR), nonmindfulness stress reduction (NMSR), or inactive control group. At posttest, inactive controls were randomly split into nonincentive and incentive controls, the latter receiving a financial reward to improve attentional performance. Pre- and postintervention, 5 validated attention paradigms were employed along with self-report scales on mindfulness and perceived stress and saliva cortisol samples to measure physiological stress. Attentional effects of MBSR, NMSR, and the financial incentive were comparable or significantly larger in the incentive group on all reaction-time-based measures. However, selective attention in the MBSR group improved significantly more than in any other group. Similarly, only the MBSR intervention improved the threshold for conscious perception and visual working memory capacity. Furthermore, stress-reducing effects of MBSR were supported because those in the MBSR group showed significantly less perceived and physiological stress while increasing their mindfulness levels significantly. We argue that MBSR may contribute uniquely to attentional improvements but that further research focusing on non-reaction-time-based measures and outcomes less confounded by test effort is needed. Critically, our data demonstrate that previously observed improvements of attention after MBSR may be seriously confounded by test effort and nonmindfulness stress reduction.

  6. A taxonomy of external and internal attention.

    Science.gov (United States)

    Chun, Marvin M; Golomb, Julie D; Turk-Browne, Nicholas B

    2011-01-01

    Attention is a core property of all perceptual and cognitive operations. Given limited capacity to process competing options, attentional mechanisms select, modulate, and sustain focus on information most relevant for behavior. A significant problem, however, is that attention is so ubiquitous that it is unwieldy to study. We propose a taxonomy based on the types of information that attention operates over--the targets of attention. At the broadest level, the taxonomy distinguishes between external attention and internal attention. External attention refers to the selection and modulation of sensory information. External attention selects locations in space, points in time, or modality-specific input. Such perceptual attention can also select features defined across any of these dimensions, or object representations that integrate over space, time, and modality. Internal attention refers to the selection, modulation, and maintenance of internally generated information, such as task rules, responses, long-term memory, or working memory. Working memory, in particular, lies closest to the intersection between external and internal attention. The taxonomy provides an organizing framework that recasts classic debates, raises new issues, and frames understanding of neural mechanisms.

    In the new digital age, information is available in large quantities.

Since information consumes primarily the attention of its recipients, the scarcity of attention is becoming the main limiting factor. In this study, we investigate the impact of advertisement pressure on a cultural market where consumers have a limited attention capacity. A model of competition for attention is developed and investigated analytically and by simulation. Advertisement is found to be much more effective when the attention capacity of agents is extremely scarce. We have observed that the market share of the advertised item improves if dummy items are introduced to the market while the strength of the advertisement is kept constant.

    2016-04-01

    Can attention alter the impression of a face? Previous studies showed that attention modulates the appearance of lower-level visual features. For instance, attention can make a simple stimulus appear to have higher contrast than it actually does. We tested whether attention can also alter the perception of a higher-order property-namely, facial attractiveness. We asked participants to judge the relative attractiveness of two faces after summoning their attention to one of the faces using a briefly presented visual cue. Across trials, participants judged the attended face to be more attractive than the same face when it was unattended. This effect was not due to decision or response biases, but rather was due to changes in perceptual processing of the faces. These results show that attention alters perceived facial attractiveness, and broadly demonstrate that attention can influence higher-level perception and may affect people's initial impressions of one another.

  17. Principles of visual attention

    DEFF Research Database (Denmark)

    Bundesen, Claus; Habekost, Thomas

    The nature of attention is one of the oldest and most central problems in psychology. A huge amount of research has been produced on this subject in the last half century, especially on attention in the visual modality, but a general explanation has remained elusive. Many still view attention...... research as a field that is fundamentally fragmented. This book takes a different perspective and presents a unified theory of visual attention: the TVA model. The TVA model explains the many aspects of visual attention by just two mechanisms for selection of information: filtering and pigeonholing....... These mechanisms are described in a set of simple equations, which allow TVA to mathematically model a large number of classical results in the attention literature. The theory explains psychological and neuroscientific findings by the same equations; TVA is a complete theory of visual attention, linking mind...

  1. Inflexible minds: impaired attention switching in recent-onset schizophrenia.

    Directory of Open Access Journals (Sweden)

    Henderikus G O M Smid

    Full Text Available Impairment of sustained attention is assumed to be a core cognitive abnormality in schizophrenia. However, this seems inconsistent with a recent hypothesis that in schizophrenia the implementation of selection (i.e., sustained attention is intact but the control of selection (i.e., switching the focus of attention is impaired. Mounting evidence supports this hypothesis, indicating that switching of attention is a bigger problem in schizophrenia than maintaining the focus of attention. To shed more light on this hypothesis, we tested whether schizophrenia patients are impaired relative to controls in sustaining attention, switching attention, or both. Fifteen patients with recent-onset schizophrenia and fifteen healthy volunteers, matched on age and intelligence, performed sustained attention and attention switching tasks, while performance and brain potential measures of selective attention were recorded. In the sustained attention task, patients did not differ from the controls on these measures. In the attention switching task, however, patients showed worse performance than the controls, and early selective attention related brain potentials were absent in the patients while clearly present in the controls. These findings support the hypothesis that schizophrenia is associated with an impairment of the mechanisms that control the direction of attention (attention switching, while the mechanisms that implement a direction of attention (sustained attention are intact.

    Self-talk interventions in sport have been receiving increased research attention in recent years. The findings have provided robust support that self-talk strategies enhance sport performance. Identifying the mechanisms that explain the beneficial effects of self-talk is important for developing a comprehensive self-talk theory and informing practice. Among the mechanisms proposed to explaining the effectiveness of self-talk, is its attentional effects. This article reviews the literature considering the effects of self-talk on attention. The findings suggest that self-talk can help enhancing attentional focus and attentional performance, but also help countering the aversive effects of distraction and ego depletion. The present evidence suggests that attention is a potential key mechanism in the self-talk performance relationship. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Attentional processes have been suggested to play a crucial role in resilience defined as positive adaptation facing adversity. However, research is lacking on associations between attentional biases to positive and threat-related stimuli, attentional control and trait resilience. Data stem from the follow-up assessment of a longitudinal study investigating mental health and related factors among German soldiers. Trait resilience was assessed with the Connor-Davidson Resilience Scale and attentional control with the Attentional Control Scale. A subset of n = 198 soldiers also completed a dot probe task with happy, neutral and threatening faces. Attentional control was positively related to trait resilience. Results revealed no associations between both attentional biases and trait resilience. However, there was a negative association between attentional bias to threat and trait resilience when attentional control was low and a positive association between attentional bias to threat and trait resilience when attentional control was high. No such associations were found for attentional bias to positive stimuli. Generalizability to other populations may be limited since we exclusively focused on male soldiers. Also, the cross-sectional design does not allow for causal conclusions. Findings suggest that attentional processing may promote trait resilience. Future research on preventive interventions should consider these findings. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2008-01-01

    Full Text Available The adaptive behavior of human beings is usually supported by rapid monitoring of outstanding events in the environment. Some investigators have suggested that a primary attention deficit might trigger symptoms of schizophrenia. In addition, researchers have long discussed the relationship between schizophrenia and the schizophrenia-like psychosis of epilepsy (SLPE. On the basis of these considerations, the objective of the present study was to investigate attention performance of patients with both disorders. Patient age was 18 to 60 years, and all patients had received formal schooling for at least four years. Patients were excluded if they had any systemic disease with neurologic or psychiatric comorbidity, or a history of brain surgery. The computer-assisted TAVIS-2R test was applied to all patients and to a control group to evaluate and discriminate between selective, alternating and sustained attention. The TAVIS-2R test is divided into three parts: one for selective attention (5 min, the second for alternating attention (5 min, and the third for the evaluation of vigilance or sustained attention (10 min. The same computer software was used for statistical analysis of reaction time, omission errors, and commission errors. The sample consisted of 36 patients with schizophrenia, 28 with interictal SLPE, and 47 healthy controls. The results of the selective attention tests for both patient groups were significantly lower than that for controls. The patients with schizophrenia and SLPE performed differently in the alternating and sustained attention tests: patients with SLPE had alternating attention deficits, whereas patients with schizophrenia showed deficits in sustained attention. These quantitative results confirmed the qualitative clinical observations for both patient groups, that is, that patients with schizophrenia had difficulties in focusing attention, whereas those with epilepsy showed perseveration in attention focus.

  10. Active suppression after involuntary capture of attention.

    Science.gov (United States)

    Sawaki, Risa; Luck, Steven J

    2013-04-01

    After attention has been involuntarily captured by a distractor, how is it reoriented toward a target? One possibility is that attention to the distractor passively fades over time, allowing the target to become attended. Another possibility is that the captured location is actively suppressed so that attention can be directed toward the target location. The present study investigated this issue with event-related potentials (ERPs), focusing on the N2pc component (a neural measure of attentional deployment) and the Pd component (a neural measure of attentional suppression). Observers identified a color-defined target in a search array, which was preceded by a task-irrelevant cue array. When the cue array contained an item that matched the target color, this item captured attention (as measured both behaviorally and with the N2pc component). This capture of attention was followed by active suppression (indexed by the Pd component), and this was then followed by a reorienting of attention toward the target in the search array (indexed by the N2pc component). These findings indicate that the involuntary capture of attention by a distractor is followed by an active suppression process that presumably facilitates the subsequent voluntary orienting of attention to the target.

    Full Text Available Abstract The global situation for people with mental illness – in developing and developed countries – is dire. Legislative and human rights protections are frequently lacking. Mental health budgets are inadequate. There are insufficient numbers of skilled policy makers, managers and clinicians. Communities are poorly informed about mental health and illness and not well organised for purposes of advocacy. In most of the world, mental health services are inaccessible or of poor quality. Most people who would benefit from psychiatric treatment and rehabilitation do not have affordable access to such services. Leadership – at all levels – for mental health system development needs to be greatly strengthened. While mental health research attention and funds are devoted predominantly to neuroscience and clinical research, we believe that the highest global mental health research priority is mental health systems research. There is an urgent need to focus on the development of effective, appropriate, affordable mental health services. The evidence base for such development is currently weak. The International Journal of Mental Health Systems aims to stimulate greater attention to the central importance of building functioning mental health systems. Rapid publication and global reach through open access will make this journal a resource for all those who wish to contribute to such development.

    2008-01-01

    Sensory physiologists and psychologists have recognized the importance of attention on human performance for more than 100 years. Since the 1970s, controlled and extensive experiments have examined effects of selective attention to a location in space or to an object. In addition to behavioral studies, cognitive neuroscientists have investigated the neural bases of attention. In this paper, I briefly review some classical attention paradigms, recent advances on the theory of attention, and some new insights from psychophysics and cognitive neuroscience. The focus is on the mechanisms of attention, that is, how attention improves human performance. Situations in which the perception of objects is unchanged, but performance may differ due to different decision structures, are distinguished from those in which attention changes the perceptual processes. The perceptual template model is introduced as a theoretical framework for analyzing mechanisms of attention. I also present empirical evidence for two attention mechanisms, stimulus enhancement and external noise exclusion, from psychophysics, neurophysiology and brain imaging.

  4. Attentional mechanisms in the generation of sympathy

    2009-06-01

    Full Text Available Empathic responses, such as sympathy towards others, are a key ingredient in the decision to provide help to those in need. The determinants of empathic responses are usually thought to be the vividness, similarity, and proximity of the victim. However, recent research highlights the role that attention plays in the generation of feelings. We expanded on this idea by investigating whether sympathy depends on cognitive mechanisms such as attention. In two studies we found that sympathy responses were lower and reaction times were longer when targets were presented with distractors. In addition, online sympathy judgments that allow attentional focusing on a target lead to greater affective responses than judgments made from memory. We conclude that attention is an ingredient in the generation of sympathy, and discuss implications for research on prosocial behaviour and the interaction between attention and emotions.

    Full Text Available Head injury is associated with psychological sequelae which impair the patient′s psychosocial functioning. Information processing, attention and memory deficits are seen in head injuries of all severity. We attempted to improve deficits of focused, sustained and divided attention. The principle of overlapping sources of attention resource pools was utilised in devising the remediation programme. Tasks used simple inexpensive materials. Four head injured young adult males with post concussion syndrome underwent the retraining program for one month. The patients had deficits of focused, sustained and divided attention parallel processing, serial processing, visual scanning, verbal learning and memory and working memory. After the retraining programme the deficits of attention improved in the four patients. Serial processing improved in two patients. Parallel processing and neuropsychological deficits did not improve in any patient. The symptom intensity reduced markedly and behavioural functioning improved in three of the four patients. The results supported an association between improving attention and reduction of symptom intensity. Attention remediation shows promise as a cost effective, time efficient and simple technique to improve the psychological and psychosocial functioning of the head injured patient.

  6. Users’ attention behaviors and features in internet forum

    Full Text Available Purpose: Attention resource is scarce. Organizing community activities in online forums faces the challenge of attracting users’ limited attention. Understanding how users of online forums allocate, maintain, and change their attentional focus and what features of online forms influence their attention behaviors is critical for effective information design. This paper seeks understanding of users’ attention behaviors and features when they participate in discussions in online forums. Design/methodology/approach: A conceptual model was established to explore the indicator system of attention’s measurement. The related attention data were collected from Alexa Access Statistics Tool and Katie community. Then this paper computed the correlation coefficient and regression relationship between the indicators of visual attention and cognitive attention. Thereafter this paper analyzed and discussed users’ attention behaviors and features in Internet forum. Findings: Relevant bivariate correlation analysis and regression analysis discovers that Internet forum's attention is mainly as visual attention in users’ early involvement. Attention resources can be transformed. In a deep participation, users’ cognitive attention is more significant. Meanwhile cognitive attention behaviors’ further development will lead to the phenomenon that cognitive attention input is prone to increase faster in the early duration. That means in-depth discussion and interaction are more likely to appear in the early stages of participation. Research limitations/implications: There are some limitations about this study. The indicators are not comprehensive enough because factors affecting the distribution of attention resources in Internet forums are complex. We didn’t distinguish different types of Internet forums when we collected the relevant data. Future research will focus more on how to obtain comprehensive attention data.

We used a dual task paradigm, in which participants made prosaccades or antisaccades and discriminated the orientation of a visual probe shown at the saccade goal, the visual cue location (antisaccade condition), or a neutral location. Moreover, participants indicated whether they had made a correct antisaccade or an erroneous prosaccade. We observed that, while spatial attention in the prosaccade task was allocated only to the saccade goal, attention in the antisaccade task was allocated both to the cued location and to the antisaccade goal. This suggests parallel attentional selection of the cued and antisaccade locations. We further observed that in error trials--in which participants made an incorrect prosaccade instead of an antisaccade--spatial attention was biased towards the prosaccade goal. These erroneous prosaccades were mostly unnoticed and were often followed by corrective antisaccades with very short latencies (parallel programming of the reflexive prosaccade to the cue and the antisaccade to the intended location. Taken together, our results suggest that attention allocation and saccade goal selection in the antisaccade task are mediated by a common competitive process.

    Full Text Available In this work, the author deals with how the issue of religion can be managed in the public space. For this, he wonders and argues whether or not the public space should be a homogeneous space from the point of view of convictions or if it can give room to heterogeneousexpressions, stemming from the plurality of profound convictions existing among the citizens. In addition, he lays out the concept of public space, discusses its “contaminations” and focuses fundamentally on its meaning as a place in which the supply, exchangeand debate of ideas, principles, intuitions, etc. are openly developed, although he devotes a little bit of attention to their most tangible or physical aspects. And he underscores the idea that in a context of democratically chosen public powers and a secular institutional framework, there should not exist privileges nor discriminations.

  18. Nonretinotopic exogenous attention.

    2011-10-25

    Attention is crucial for visual perception because it allows the visual system to effectively use its limited resources by selecting behaviorally and cognitively relevant stimuli from the large amount of information impinging on the eyes. Reflexive, stimulus-driven attention is essential for successful interactions with the environment because it can, for example, speed up responses to life-threatening events. It is commonly believed that exogenous attention operates in the retinotopic coordinates of the early visual system. Here, using a novel experimental paradigm [1], we show that a nonretinotopic cue improves both accuracy and reaction times in a visual search task. Furthermore, the influence of the cue is limited both in space and time, a characteristic typical of exogenous cueing. These and other recent findings show that many more aspects of vision are processed nonretinotopically than previously thought.

    Full Text Available This position paper argues how there has to be much more to smart city learning than just wayshowing, and something better as augmented reality than covering the world with instructions. Attention has become something for many people to know better in an age of information superabundance. Embodied cognition explains how the work-ings of attention are not solely a foreground task, as if attention is something to pay. As digital media appear in ever more formats and contexts, their hybrids with physical form increasing influence how habitual engagement with persistent situations creates learning. Ambient information can just add to the distraction by multitasking, or it can support more favorable processes of shifting among different kinds of information with a particular intent. As one word for this latter process, foraging deserves more consideration in smart city learning

    A neurodynamical model for selective visual attention considering orientation preference is proposed. Since orientation preference is one of the most important properties of neurons in the primary visual cortex, it should be fully considered besides external stimuli intensity. By tuning the parameter of orientation preference, the regimes of synchronous dynamics associated with the development of the attention focus are studied. The attention focus is represented by those peripheral neurons that generate spikes synchronously with the central neuron while the activity of other peripheral neurons is suppressed. Such dynamics correspond to the partial synchronization mode. Simulation results show that the model can sequentially select objects with different orientation preferences and has a reliable shift of attention from one object to another, which are consistent with the experimental results that neurons with different orientation preferences are laid out in pinwheel patterns.%A neurodynamical model for selective visual attention considering orientation preference is proposed.Since orientation preference is one of the most important properties of neurons in the primary visual cortex,it should be fully considered besides external stimuli intensity.By tuning the parameter of orientation preference,the regimes of synchronous dynamics associated with the development of the attention focus are studied.The attention focus is represented by those peripheral neurons that generate spikes synchronously with the central neuron while the activity of other peripheral neurons is suppressed.Such dynamics correspond to the partial synchronization mode.Simulation results show that the model can sequentially select objects with different orientation preferences and has a reliable shift of attention from one object to another,which are consistent with the experimental results that neurons with different orientation preferences are laid out in pinwheel patterns.Selective visual

    Full Text Available The present article develops an immanent critique of the attention economy as a power apparatus. In particular, it contends that what Foucault (2009 defined as the passage from disciplinary societies to societies of security entails a transformation of the main function of human attention: whereas in disciplinary societies attention (or the gaze was aimed at imposing continuous surveillance on each individual, societies of security conceive the gaze of each subject as a source of data which allows constructing a new object of power, i.e., the population. To illustrate this, the present article focuses on the specific case of the attention economy and the notions of ‘dataveillance’ and ‘Big Data’.

    2013-04-01

    Social computing focuses on the interaction between social behavior and information, especially on how the latter propagates across social networks and is consumed and transformed in the process. At the same time the ubiquity of information has left it devoid of much monetary value. The scarce, and therefore valuable, resource is now attention, and its allocation gives rise to an attention economy that determines how content is consumed and propagated. Since two major factors involved in getting attention are novelty and popularity, we analyze the role that both play in attracting attention to web content and how to prioritize them in order to maximize it. We also demonstrate that the relative performance of strategies based on prioritizing either popularity or novelty exhibit an abrupt change around a critical value of the novelty decay time, resembling a phase transition.

    Effective filtering of distractor information has been shown to be dependent on perceptual load. Given the salience of emotional information and the presence of emotion-attention interactions, we wanted to explore the recognition memory for emotional distractors especially as a function of focused attention and distributed attention by manipulating load and the spatial spread of attention. We performed two experiments to study emotion-attention interactions by measuring recognition memory performance for distractor neutral and emotional faces. Participants performed a color discrimination task (low-load) or letter identification task (high-load) with a letter string display in Experiment 1 and a high-load letter identification task with letters presented in a circular array in Experiment 2. The stimuli were presented against a distractor face background. The recognition memory results show that happy faces were recognized better than sad faces under conditions of less focused or distributed attention. When attention is more spatially focused, sad faces were recognized better than happy faces. The study provides evidence for emotion-attention interactions in which specific emotional information like sad or happy is associated with focused or distributed attention respectively. Distractor processing with emotional information also has implications for theories of attention.

    Koenig, Sebastian; Wolf, Reinhard; Heisenberg, Martin

    2016-01-01

    A visual stimulus at a particular location of the visual field may elicit a behavior while at the same time equally salient stimuli in other parts do not. This property of visual systems is known as selective visual attention (SVA). The animal is said to have a focus of attention (FoA) which it has shifted to a particular location. Visual attention normally involves an attention span at the location to which the FoA has been shifted. Here the attention span is measured in Drosophila. The fly is tethered and hence has its eyes fixed in space. It can shift its FoA internally. This shift is revealed using two simultaneous test stimuli with characteristic responses at their particular locations. In tethered flight a wild type fly keeps its FoA at a certain location for up to 4s. Flies with a mutation in the radish gene, that has been suggested to be involved in attention-like mechanisms, display a reduced attention span of only 1s.

  18. Spatial attention in written word perception

    Directory of Open Access Journals (Sweden)

    Veronica eMontani

    2014-02-01

    Full Text Available The role of attention in visual word recognition and reading aloud is a long debated issue. Studies of both developmental and acquired reading disorders provide growing evidence that spatial attention is critically involved in word reading, in particular for the phonological decoding of unfamiliar letter strings. However, studies on healthy participants have produced contrasting results. The aim of this study was to investigate how the allocation of spatial attention may influence the perception of letter strings in skilled readers. High frequency words, low frequency words and pseudowords were briefly and parafoveally presented either in the left or the right visual field. Attentional allocation was modulated by the presentation of a spatial cue before the target string. Accuracy in reporting the target string was modulated by the spatial cue but this effect varied with the type of string. For unfamiliar strings, processing was facilitated when attention was focused on the string location and hindered when it was diverted from the target. This finding is consistent the assumptions of the CDP+ model of reading aloud, as well as with familiarity sensitivity models that argue for a flexible use of attention according with the specific requirements of the string. Moreover, we found that processing of high-frequency words was facilitated by an extra-large focus of attention. The latter result is consistent with the hypothesis that a broad distribution of attention is the default mode during reading of familiar words because it might optimally engage the broad receptive fields of the highest detectors in the hierarchical system for visual word recognition.

The article suggests that further public education about net neutrality would be beneficial. The first portion of this paper provides a survey of the existing literature surrounding net neutrality, highlighting the contentious debate between market-based and public interest perspectives. In order to contextualize the debate, an overview of public utility philosophy is provided, shedding light on how the Internet can be conceptualized as a public good. Following this discussion, an analysis of mainstream media is presented, exploring how the media represents the issue of net neutrality and whether or not the Internet is discussed through the lens of public utility. To further examine how the net neutrality debate is being addressed, and to see the potential impacts of media discourses on the general public, the results of a focus group are reported and analyzed. Finally, a discussion assesses the implications of the net neutrality debate as presented through media discourses, highlighting the future of net neutrality as an important policy issue.

    The capacity to stabilize the content of attention over time varies among individuals, and its impairment is a hallmark of several mental illnesses. Impairments in sustained attention in patients with attention disorders have been associated with increased trial-to-trial variability in reaction time and event-related potential deficits during attention tasks. At present, it is unclear whether the ability to sustain attention and its underlying brain circuitry are transformable through training. Here, we show, with dichotic listening task performance and electroencephalography, that training attention, as cultivated by meditation, can improve the ability to sustain attention. Three months of intensive meditation training reduced variability in attentional processing of target tones, as indicated by both enhanced theta-band phase consistency of oscillatory neural responses over anterior brain areas and reduced reaction time variability. Furthermore, those individuals who showed the greatest increase in neural response consistency showed the largest decrease in behavioral response variability. Notably, we also observed reduced variability in neural processing, in particular in low-frequency bands, regardless of whether the deviant tone was attended or unattended. Focused attention meditation may thus affect both distracter and target processing, perhaps by enhancing entrainment of neuronal oscillations to sensory input rhythms, a mechanism important for controlling the content of attention. These novel findings highlight the mechanisms underlying focused attention meditation and support the notion that mental training can significantly affect attention and brain function.

    Attention difficulties are a common clinical complaint among children with epilepsy. We aimed to compare a range of attentional abilities between groups of children with two common epilepsy syndromes, Temporal Lobe Epilepsy (TLE) and Idiopathic Generalized Epilepsy (IGE), and to healthy controls. We also investigated whether epilepsy factors (laterality of seizure focus, epilepsy onset, duration, and severity) were related to attentional abilities. Multiple dimensions of attention (selective, sustained, and divided attention and attentional control) were assessed directly with standardized neuropsychological measures in 101 children aged 6-16years (23 children with TLE, 20 with IGE and 58 healthy controls). Attention was also assessed indirectly, via a parent-report measure. Children with TLE performed worse than children with IGE (p=0.013) and healthy controls (pattentional control, but no between-group differences were apparent on tests of other attentional abilities. Compared to healthy controls, greater attention problems were reported by parents of children with TLE (p=0.006) and IGE (p=0.012). Left-hemisphere seizure focus and greater epilepsy severity were associated with poorer attentional control and sustained-divided attention, respectively, but no other epilepsy factors were associated with attentional abilities. These findings suggest that children with localization-related epilepsy, but not generalized epilepsy, may be at risk of deficits in attentional control. Interventions aimed at improving attentional control may be targeted at children with localization-related epilepsy, particularly those with a left-hemisphere seizure focus, who appear to be particularly susceptible to this type of attentional deficit.

    In this research, we investigated whether attention operates in the encoding of automatized information, the retrieval of automatized information, or in both cases. Subjects searched two-word displays for members of a target category in focused-attention or divided-attention conditions that were crossed with block (training vs. transfer). To see whether subjects encoded all available items or only attended items, we compared performance for subjects in different training conditions but in the same transfer condition. Subjects encoded attended items. To see whether subjects retrieved all the items they had in memory, or only items associated with that to which they were attending at retrieval, we compared performance for subjects in the same training conditions but in different transfer conditions. Subjects retrieved attended items. Attention was found to operate at both encoding and retrieval. These findings support the instance theory of automaticity, which predicts the role of attention at encoding and retrieval.

    2012-01-01

    Mindfulness-based meditation practices involve various attentional skills, including the ability to sustain and focus ones attention. During a simple mindful breathing practice, sustained attention is required to maintain focus on the breath while cognitive control is required to detect mind wandering. We thus hypothesized that regular, brief mindfulness training would result in improvements in the self-regulation of attention and foster changes in neuronal activity related to attentional con...

    We review and relate two literatures on the development of attention in children: one concerning flexible attention switching and the other concerning selective attention. The first is a growing literature on preschool children’s performances in an attention switching task indicating that children become more flexible in their attentional control during the preschool years. The second literature encompasses a large and robust set of phenomena for the same developmental period that indicate a ...

    Recent findings indicate that conscious attention is related to large-scale information integration of various brain regions, including both hemispheres, that enables integration of parallel distributed modalities of processed information. There is also evidence that the level of information transference related to integration or splitting among brain regions, and between hemispheres, establishes a certain level of efficiency of the information processing. The level of information transference also may have modulatory influences on attentional capacity that are closely linked to the emotional arousal and autonomic response related to a stimulus. These findings suggest a hypothesis that changes in conscious attention, specifically during meditation could be reflected in the autonomic activity as the left-right information transference calculated from bilateral electrodermal activity (EDA). With the aim to compare conscious attention during meditation with other attentional states (resting state, Stroop task, and memory task), we performed bilateral EDA measurement in 7 healthy persons during resting state, Stroop task, neurofeedback memory test, and meditation. The results indicate that the information transference (ie, transinformation) is able to distinguish those attentional states, and that the highest level of the transinformation has been found during attentional processing related to meditation, indicating higher level of connectivity between left and right sides. Calculations other than pointwise transinformation (PTI) performed on EDA records, such as mean skin conductance level or laterality index, were not able to distinguish attentional states. The results suggest that PTI may present an interesting method useful for the assessment of information flow, related to neural functioning, that in the case of meditation may reflect typical integrative changes in the autonomic nervous system related to brain functions and focused attentional processing.

    2015-09-01

    Attention is a means of flexibly selecting and enhancing a subset of sensory input based on the current behavioral goals. Numerous signatures of attention have been identified throughout the brain, and now experimenters are seeking to determine which of these signatures are causally related to the behavioral benefits of attention, and the source of these modulations within the brain. Here, we review the neural signatures of attention throughout the brain, their theoretical benefits for visual processing, and their experimental correlations with behavioral performance. We discuss the importance of measuring cue benefits as a way to distinguish between impairments on an attention task, which may instead be visual or motor impairments, and true attentional deficits. We examine evidence for various areas proposed as sources of attentional modulation within the brain, with a focus on the prefrontal cortex. Lastly, we look at studies that aim to link sources of attention to its neuronal signatures elsewhere in the brain.

    2015-06-11

    The commercial sexual exploitation of children ("CSEC") is an egregious human rights and public health violation that occurs every day across the US. Although there has been positive change in the US to bring attention to CSEC and to reform laws and policies to assist CSEC victims, scant attention and resources have been dedicated to prevention efforts. This paper critiques current US strategies to address CSEC and highlights the limitations of an interventionist framework that narrows its focus to anti-trafficking efforts. As an alternative, the paper proposes a human rights-based approach focusing on the fulfillment of economic and social rights of children as a prevention strategy in the U.S.

  2. Minds "at attention": mindfulness training curbs attentional lapses in military cohorts.

    Directory of Open Access Journals (Sweden)

    Amishi P Jha

    Full Text Available We investigated the impact of mindfulness training (MT on attentional performance lapses associated with task-unrelated thought (i.e., mind wandering. Periods of persistent and intensive demands may compromise attention and increase off-task thinking. Here, we investigated if MT may mitigate these deleterious effects and promote cognitive resilience in military cohorts enduring a high-demand interval of predeployment training. To better understand which aspects of MT programs are most beneficial, three military cohorts were examined. Two of the three groups were provided MT. One group received an 8-hour, 8-week variant of Mindfulness-based Mind Fitness Training (MMFT emphasizing engagement in training exercises (training-focused MT, n = 40, a second group received a didactic-focused variant emphasizing content regarding stress and resilience (didactic-focused MT, n = 40, and the third group served as a no-training control (NTC, n = 24. Sustained Attention to Response Task (SART performance was indexed in all military groups and a no-training civilian group (CIV, n = 45 before (T1 and after (T2 the MT course period. Attentional performance (measured by A', a sensitivity index was lower in NTC vs. CIV at T2, suggesting that performance suffers after enduring a high-demand predeployment interval relative to a similar time period of civilian life. Yet, there were significantly fewer performance lapses in the military cohorts receiving MT relative to NTC, with training-focused MT outperforming didactic-focused MT at T2. From T1 to T2, A' degraded in NTC and didactic-focused MT but remained stable in training-focused MT and CIV. In sum, while protracted periods of high-demand military training may increase attentional performance lapses, practice-focused MT programs akin to training-focused MT may bolster attentional performance more than didactic-focused programs. As such, training-focused MT programs should be further examined in cohorts

    Compared to European-Americans, African-Americans have greater probability of becoming infected with HIV, as well as worse outcomes when they become infected. Therefore, adequate health communications should ensure that they capture the attention of African-Americans and do not perpetuate disadvantages relative to European-Americans. The objective of this report was to examine if racial disparities in attention to health information parallel racial disparities in health outcomes. Participants were clients of a public health clinic (Study 1 n = 64; Study 2 n = 55). Unobtrusive observation in a public health waiting room, message reading times, and response-time on a modified flanker task were used to examine attention to HIV- and flu-information across racial groups. In Study 1, participants were observed for the duration of their time in a public health clinic waiting room (average duration: 31 min). In Study 2, participants completed tasks in a private room at the public health clinic (average duration: 21 min). Across all attention measures, results suggest an interaction between race and information type on attention to health information. In particular, African-Americans differentially attended to information as a function of information type, with decreased attention to HIV- versus flu-information. In contrast, European-Americans attended equally to both HIV- and flu-information. As such, disparities in attention yielded less access to certain health information for African- than European-Americans in a health setting. The identified disparities in attention are particularly problematic because they disadvantage African-Americans at a time of great effort to correct racial disparities. Modifying the framing of health information in ways that ensure attention by all racial groups may be a strategy to increase attention, and thereby reduce disparities in health outcomes. Future research should find solutions that increase attentional access to health

  4. The role of somatic threat feature detectors in the attentional bias toward pain: effects of spatial attention.

    Science.gov (United States)

    Dowman, Robert

    2011-03-01

    Our previous work suggests that somatic threat feature detectors indexed by a pain-evoked midlatency negative scalp potential play an important role in the attentional bias toward pain. In these studies the somatic threat feature detectors facilitated the shift in attention to a somatic threat when attention was focused on another stimulus modality but not when it was focused on another spatial location. This experiment used the Posner cuing paradigm to investigate possible explanations for this discrepancy. The results demonstrate that the different somatic threat effects observed in previous modal and spatial cuing studies are not due to attentional set. Rather, this discrepancy may be related to differences in contingent attention capture. This study also verifies earlier findings suggesting that some of the pain-related P2 component generators are involved in stimulus-driven shifts in spatial attention toward task-relevant stimuli.

  5. Translating social work research for social justice: focusing translational research on equity rather than the market.

    2014-01-01

    Management of the dissemination of effective interventions in social work is often uncertain, and even when attention is paid to diffusing effective, innovative interventions, the focus is often disproportionately on a marketplace orientation of increasing the market share of branded, manualized interventions and social service treatment products. Public health frameworks of dissemination can improve knowledge translation in social interventions by focusing dissemination efforts on achieving equity and increasing the availability of effective interventions to all those who can benefit from them rather than simply focusing on commercial processes. This article identifies three equity-focused translation frameworks that can aid the dissemination of effective social interventions at the macro-, meso-, and micro-levels. Implications for policy and practice are discussed.

    2010-11-01

    Full Text Available The present study examined the hypothesis that feedback inducing an external focus of attention enhances motor learning if it is provided frequently (i.e., 100% rather than less frequently. Children (10-12 year olds practiced a soccer throw-in task and were provided feedback about movement form. The feedback statements, provided either after every (100% or every third (33% practice trial, were similar in content but induced either an internal focus (body-movement related or external focus (movement-effect related. The results demonstrated that learning of the movement form was enhanced by external-focus feedback after every trial (100% relative to external-focus feedback after every third trial (33% or internal-focus feedback (100%, 33%, as demonstrated by immediate and delayed transfer tests without feedback. There was no difference between the two internal-focus feedback groups. These findings indicate that the attentional focus induced by feedback is an important factor in determining the effectiveness of different feedback frequencies. We argue that the informational properties of feedback cannot sufficiently account for these and related findings, and suggest that the attentional role of feedback be given greater consideration in future studies.

    Models of attention often distinguish among attention subtypes, with classic models separating orienting, switching, and sustaining functions. Compared with other forms of attention, the neurophysiological basis of sustaining attention has received far less notice, yet it is known that momentary failures of sustained attention can have far-ranging negative effects in healthy individuals, and lasting sustained attention deficits are pervasive in clinical populations. In recent years, however, there has been increased interest in characterizing moment-to-moment fluctuations in sustained attention, in addition to the overall vigilance decrement, and understanding how these neurocognitive systems change over the life span and across various clinical populations. The use of novel neuroimaging paradigms and statistical approaches has allowed for better characterization of the neural networks supporting sustained attention and has highlighted dynamic interactions within and across multiple distributed networks that predict behavioral performance. These advances have also provided potential biomarkers to identify individuals with sustained attention deficits. These findings have led to new theoretical models explaining why sustaining focused attention is a challenge for individuals and form the basis for the next generation of sustained attention research, which seeks to accurately diagnose and develop theoretically driven treatments for sustained attention deficits that affect a variety of clinical populations. © 2017 New York Academy of Sciences.

    Individuals with high working memory (WM) capacity also tend to have better selective and divided attention. Although both capacities are essential for skilled performance in many areas, evidence for potential training and expertise effects is scarce. We investigated the attentional flexibility of musical conductors by comparing them to equivalently trained pianists. Conductors must focus their attention both on individual instruments and on larger sections of different instruments. We studied students and professionals in both domains to assess the contributions of age and training to these skills. Participants completed WM span tests for auditory and visual (notated) pitches and timing durations, as well as long-term memory tests. In three dichotic attention tasks, they were asked to detect small pitch and timing deviations from two melodic streams presented in baseline (separate streams), selective-attention (concentrating on only one stream), and divided-attention (concentrating on targets in both streams simultaneously) conditions. Conductors were better than pianists in detecting timing deviations in divided attention, and experts detected more targets than students. We found no group differences for WM capacity or for pitch deviations in the attention tasks, even after controlling for the older age of the experts. Musicians' WM spans across multimodal conditions were positively related to selective and divided attention. High-WM participants also had shorter reaction times in selective attention. Taken together, conductors showed higher attentional flexibility in successfully switching between different foci of attention.

    Kulkarni, Madhuri

    2015-03-01

    Attention Deficit Hyperactivity Disorder (ADHD) is a common behavioral disorder in children. It is characterized by motor hyperactivity, impulsivity and inattention inappropriate for the age. Approximately 5-10 % of school age children are diagnosed to have ADHD. The affected children show significant impairment in social behavior and academic performance. The DSM-5 criteria are useful in diagnosing three subtypes of ADHD based on presence of symptoms described in 3 domains viz ., inattention, hyperactivity and impulsivity. Co-morbidities like specific learning disability, anxiety disorder, oppositional defiant disorder are commonly associated with ADHD.Education of parents and teachers, behavioral therapy and medication are main components of management. Methylphenidate and Atomoxetine are effective in controlling symptoms of ADHD in most children. Research studies estimated that 30-60 % of children continue to show symptoms of ADHD in adulthood. The general practitioner can play an important role in early diagnosis, appropriate assessment and guiding parents for management of children with ADHD.

    2010-01-01

    Attentional dyslexia is a reading deficit in which letters migrate between neighboring words, but are correctly identified and keep their correct relative position within the word. Thus, for example, fig tree can be read as fig free or even tie free. This study reports on 10 Hebrew-speaking individuals with developmental attentional dyslexia and explores in detail the characteristics of their between-word errors. Each participant read 2290 words, presented in word pairs: 845 horizontally presented word pairs, 240 vertically presented word pairs, and 60 nonword pairs. The main results are that almost all migrations preserve the relative position of the migrating letter within the word, indicating that the between-word position can be impaired while the within-word position encoding remains intact. This result is also supported by the finding that the participants did not make many letter position errors within words. Further analyses indicated that more errors occur in longer words, that most migrations occur in final letters (which are the leftmost letters in Hebrew), and that letters migrate both horizontally and vertically, and more frequently from the first to the second word in horizontal presentation. More migrations occurred when the result of migration was an existing word. Similarity between words in a pair did not increase error rates, and more migrations occurred when the words shared fewer letters. The between-word errors included the classic errors of migration of a letter between words, but also omission of one instance of a letter that appeared in the same position in the two words, an error that constituted a considerable percentage of the between-word errors, and intrusion of a letter from one word to the corresponding position in the neighboring word without erasing the original letter in the same position.

  3. Relevance as Social Matrix of Attention in Alfred Schutz

    Directory of Open Access Journals (Sweden)

    Enrico Campo

    2016-01-01

    Full Text Available Attention is a critical faculty in contemporary Western societies. What is surprising is the fact that attention has been mainly analyzed as an individual phenomenon. Scientific research that treats attention exclusively on the individual level simplifies an enormously complex situation. Instead, according to the idea defended in this essay, one cannot think of attention and perception without regard for cultural conventions and social norms. This article therefore proposes to investigate attention precisely in its social dimension. In particular, the specific objective is to highlight the contribution Alfred Schutz’s theory of systems of relevance can give to the understanding of the social mechanisms that regulate attention. In order to demonstrate the viability of the Schutzian proposal, here are discussed some recent perspectives that explore the mechanisms of the social regulation of attention. The article will briefly revisit these contributions that explicitly investigate intersubjective and collective attention, and will focus especially on the proposals of Eviatar Zerubavel and Yves Citton. Then is analyzed the role of attention in the theoretical edifice of Schutz, to focus on the relationship between attention and systems of relevance.

    Full Text Available Public Service Motivation concept was developed in North America and focuses on specific motivations of public servants, such as employee satisfaction, organizational commitment, reward preferences, organizational and individual performance. Other types of motivation, as financial consideration, are relevant but have less important influences with regard to this kind of work outcomes. This strengthen the assertion for a diversified motivational strategy, which affect various types of motivation, while not losing sight of the public value that one organization shows and therefore valuing public service motivation as a specific contribution to work outcomes. The concept has been increasingly applied in European public administration. This paper presents Status Quo of international Public Service Motivation research and locates in them empirical evidences from contries that are already working with this concept, like Austria. It also analyses implications for central questions of public management. The main focus of this article is general appropriateness and possible applications for Romanian public management research.

    The continual exposure to unhealthy food cues in the environment encourages poor dietary habits, in particular consuming too much fat and sugar, and not enough fruit and vegetables. According to Berridge's (2009) model of food reward, unhealthy eating is a behavioural response to biased attentional processing. The present study used an established attentional bias modification paradigm to discourage the consumption of unhealthy food and instead promote healthy eating. Participants were 146 undergraduate women who were randomly assigned to two groups: one was trained to direct their attention toward pictures of healthy food ('attend healthy' group) and the other toward unhealthy food ('attend unhealthy' group). It was found that participants trained to attend to healthy food cues demonstrated an increased attentional bias for such cues and ate relatively more of the healthy than unhealthy snacks compared to the 'attend unhealthy' group. Theoretically, the results support the postulated link between biased attentional processing and consumption (Berridge, 2009). At a practical level, they offer potential scope for interventions that focus on eating well. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Based on Posner's (1994) model of attentional functions, the relationship between age and personal proneness to attention-related errors while driving and the functioning of the 3 attentional networks were explored by means of attentional behavioral measures and self-report data. A sample of 55 drivers was drawn from the general population of Mar del Plata, Buenos Aires, Argentina. The Attention Network Test for Interactions (ANTI) (Callejas et al. 2004) task was used to obtain behavioral measures of the attentional networks, and we used the Attention-Related Driving Error Scale (ARDES) (Ledesma et al. 2010) questionnaire to obtain a self-report measure of attention-related driving errors. Drivers reporting the greatest propensity to experience attention-related errors showed an overall slowdown in performance, less endogenous preparation for high = priority warning signs, and a better response to conflict in the presence of valid cues than drivers less prone to attention-related errors while driving. Older participants showed a slowdown in performance, less endogenous preparation for high-priority warning signs, and worse cognitive control when solving conflict in comparison with younger drivers. We suggest that each group variable, attention-related error proneness and age, shows a particular combination of attentional network functioning that implies different ways of being distracted, which have different practical implications for safe driving. It can be inferred that drivers who are more prone to commit attentional errors while driving run less risk in situations in which they can deal with response conflict in the presence of valid cues because of the particular way in which their attentional networks are combined when a valid cue is present, could serve to compensate, with a better response conflict, their general slowdown and less endogenous preparedness for high-priority signs. It can be inferred that older drivers might show a reduction of the general

    Issue addressed: Unwanted sexual attention and unhealthy intimate relationships have the potential to have serious negative health consequences. To date, there has been scant focus on these issues among university students in Australia. The aim of the current study was to describe the extent of unwanted sexual attention and unhealthy intimate relationships experienced in their lifetime by female university students aged 18-25 years.Methods: A cross-sectional study was undertaken involving 465 female students aged 18-25 years. Students were recruited through one faculty within a Victorian university and invited to complete an anonymous online questionnaire.Results: Sixty-seven per cent (n = 312) of female students reported experiencing unwanted sexual attention in their lifetime. The most common form of unwanted sexual attention was kissing or touching over clothes (98%; n = 306). Over 43% (n = 124) of the female students reported that the experience of unwanted sexual experience occurred after their protests were ignored. Thirty per cent (n = 135) of the female students reported experiencing at least one element of an unhealthy intimate relationship.Conclusions: The high rates of unwanted sexual attention and unhealthy intimate relationships among female university students is of concern given the negative impact such events can have on individual's physical, emotional and social well being.So what?: Public health and health promotion action is required to prevent female students from experiencing unwanted sexual attention and unhealthy intimate relationships, and to address the negative health and well being consequences.

  13. The effects of sequential attention shifts within visual working memory

    Full Text Available Previous studies have shown conflicting data as to whether it is possible to sequentially shift spatial attention among visual working memory (VWM representations. The present study investigated this issue by asynchronously presenting attentional cues during the retention interval of a change detection task. In particular, we focused on two types of sequential attention shifts: 1 orienting attention to one location, and then withdrawing attention from it, and 2 switching the focus of attention from one location to another. In Experiment 1, a withdrawal cue was presented after a spatial retro-cue to measure the effect of withdrawing attention. The withdrawal cue significantly reduced the cost of invalid spatial cues, but surprisingly, did not attenuate the benefit of valid spatial cues. This indicates that the withdrawal cue only triggered the activation of facilitative components but not inhibitory components of attention. In Experiment 2, two spatial retro-cues were presented successively to examine the effect of switching the focus of attention. We observed benefits of both the first and second cues in sequential cueing, indicating that participants were able to reorient attention from one location to another within VWM, and the reallocation of attention did not attenuate memory at the first cued location. In Experiment 3, we found that reducing the validity of the preceding spatial cue did lead to a significant reduction in its benefit. However, performance at the first-cued location was still better than the neutral baseline or performance at the uncued locations, indicating that the first cue benefit might have been preserved both partially under automatic control and partially under voluntary control. Our findings revealed new properties of dynamic attentional control in VWM maintenance.

    Public participation has received increasing attention in environmental policy making world wide. Yet research has been inadequate to answer fundamental questions about how successful past programs have been, what factors lead to success, and where efforts to improve public involvement should focus. To address these questions, we examine the case study record of public participation efforts in the United States over the last 30 years. We evaluate the success of numerous examples of public participation in environmental decision making and identify the factors that lead to success. The paper deals with a number of themes, including: The extent to which participation can incorporate public values into decision making, improve the substantive quality of decisions, reduce conflict, increase trust in institutions, and educate and inform the public; What can be expected from different approaches to public participation, such as public meetings, advisory committees, and mediation; The relative importance of the participatory process vs. the context in which participation takes place; Procedural features of particular importance; and The relationship between participation and implementation. The paper provides general results that can be used to guide the improvement of public participation programs, support assessment of innovative methods, and advance the theoretical understanding of public participation.

    Attention deficit hyperactivity disorder (ADHD) is one of the most common childhood psychiatric disorders and can persist into the adulthood. ADHD has important social, academic and occupational consequences. ADHD diagnosis is based on the fulfillment of several clinical criteria, which can vary depending on the diagnostic system used. The clinical presentation can show great between-patient variability and it has been related to a dysfunction in the fronto-striatal and meso-limbic circuits. Recent investigations support a model in which multiple genetic and environmental factors interact to create a neurobiological susceptibility to develop the disorder. However, no clear causal association has yet been identified. Although multimodal treatment including both pharmacological and psychosocial interventions is usually recommended, no convincing evidence exists to support this recommendation. Pharmacological treatment has fundamentally shown to improve ADHD symptoms in the short term, while efficacy data for psychosocial interventions are scarce and inconsistent. Yet, drug treatment is increasingly popular and the last 2 decades have witnessed a sharp increase in the prescription of anti-ADHD medications coinciding with the marketing of new drugs to treat ADHD.

  17. Attention Networks and Consciousness

    Full Text Available The term consciousness is an important one in the vernacular of the western literature in many fields. It is no wonder that scientists have assumed that consciousness will be found as a component of the human brain and that we will come to understand its neural basis. However, there is rather little in common between consciousness as the neurologist would use it to diagnose the vegetative state, how the feminist would use it to support raising male consciousness of the economic plight of women and as the philosopher would use it when defining the really hard question of the subjective state of awareness induced by sensory qualities. When faced with this kind of problem it is usual to subdivide the term into more manageable perhaps partly operational definitions. Three meanings that capture aspects of consciousness are: (1 the neurology of the state of mind allowing coherent orientation to time and place (2 the selection of sensory or memorial information for awareness and (3 the voluntary control over overt responses. In each of these cases the mechanisms of consciousness overlap with one or more of the attentional networks that have been studied with the methods of cognitive neuroscience. In this paper we explore t

  20. Assessing the Effect of China's National Publicity Films from the Perspective of Public Diplomacy

    Full Text Available This article empirically assessed the effect of China’s national publicity film launched in Times Square in Manhattan, New York. To this end, the author gave a set of general criteria and indicators to measure the effect of national publicity films. Whether the publicity film was effective depends on whether American people’s image perceptions of China were improved after it was launched. Quantitative indicators are: the number of reports in the target country and the predispositions of the reports; the target country people’s participation and their predispositions; and the real behavior of the target country people. The analysis revealed that the 2011 national publicity film did not achieve the anticipated effect. The number of U.S. mainstream media reports was less than expected and their evaluations were quite negative; the participation of American people was low and the extent of the favorability both of the publicity film and China was not high; and the launch of the publicity film did not trigger a travel boom to China. Accordingly, this article suggested that the future implementation of China’s national publicity films focuses on two aspects: first, pay attention to cultural differences and enhance the comprehensibility of the discourse; second, practice what it preaches and strengthen the credibility of the discourse.
